Cant see data in cells in tableview after setItems()

Question

I am trying to put my test ObservableList data into JavaFX TableView i made with scene builder, but when i use setItems() i can see there are 5 rows of data, but cells in that row dont contain any data or at least i cant see it

private final ObservableList<tblQuery> data =
        FXCollections.observableArrayList(
                new tblQuery("Jacob", "Smith", "jacob.smith@example.com"),
                //4 more rows
        );
private javafx.scene.control.TableView<tblQuery> tableview;

@Override
public void start(Stage primaryStage) throws Exception {
    FXMLLoader loader = new FXMLLoader(getClass().getResource("sample.fxml"));
    Parent root = loader.load();
    tableview = (TableView) loader.getNamespace().get("tabQuery");
    primaryStage.setTitle("Cycle reloader");
    primaryStage.setResizable(false);
    primaryStage.setScene(new Scene(root));

    tableview.setEditable(true);

    TableColumn coID = new TableColumn("Cycle№");
    coID.setMinWidth(80);
    coID.setCellValueFactory(
            new PropertyValueFactory<tblQuery, String>("id"));

    //workflow and date columns, same as id column

    tableview.setItems(data);
    tableview.getColumns().addAll(coID, colWorkflow, colDate);

    primaryStage.show();

}

public class tblQuery {
    private final SimpleStringProperty id;
    private final SimpleStringProperty workflow;
    private final SimpleStringProperty date;

    private tblQuery(String id, String workflow, String date) {
        this.id = new SimpleStringProperty(id);
        this.workflow = new SimpleStringProperty(workflow);
        this.date = new SimpleStringProperty(date);
    }

    public String getID() {
        return id.get();
    }

    public void setID(String fName) {
        id.set(fName);
    }

    public String getWorkflow() {
        return workflow.get();
    }

    public void setWorkflow(String fName) {
        workflow.set(fName);
    }

    public String getDate() {
        return date.get();
    }

    public void setDate(String fName) {
        date.set(fName);
    }
}

and all i can see is:

i can select any row above selected, but cant go down with selection

getID() is misspelled. It is suppose to be getId() in order to follow the bean convention. Here is modified working example.

    import javafx.application.Application;
    import javafx.collections.FXCollections;
    import javafx.collections.ObservableList;
    import javafx.scene.Scene;
    import javafx.scene.control.TableColumn;
    import javafx.scene.control.TableView;
    import javafx.scene.control.cell.PropertyValueFactory;
    import javafx.stage.Stage;

    public class TableApp extends Application {

        private final ObservableList<TblQuery> data =
                FXCollections.observableArrayList(
                        new TblQuery("Jacob", "Smith", "jacob.smith@example.com"),
                        new TblQuery("Isabella", "Johnson", "isabella.johnson@example.com"),
                        new TblQuery("Ethan", "Williams", "ethan.williams@example.com"),
                        new TblQuery("Emma", "Jones", "emma.jones@example.com"),
                        new TblQuery("Michael", "Brown", "michael.brown@example.com")
                );

        private javafx.scene.control.TableView<TblQuery> tableview = new TableView<>();

        public static void main(String[] args) {
            launch(args);
        }

        @Override
        public void start(Stage primaryStage) throws Exception {
            primaryStage.setTitle("Cycle reloader");
            primaryStage.setResizable(false);
            primaryStage.setScene(new Scene(tableview));

            tableview.setEditable(true);

            TableColumn idCol = new TableColumn("What");
            idCol.setMinWidth(80);
            idCol.setCellValueFactory(
                    new PropertyValueFactory<TblQuery, String>("id"));

            TableColumn workflowCol = new TableColumn("Workflow name");
            workflowCol.setMinWidth(236);
            workflowCol.setCellValueFactory(
                    new PropertyValueFactory<TblQuery, String>("workflow"));

            TableColumn dateCol = new TableColumn("AS OF DAY");
            dateCol.setMinWidth(80);
            dateCol.setCellValueFactory(
                    new PropertyValueFactory<TblQuery, String>("date"));

            tableview.setItems(data);
            tableview.getColumns().addAll(idCol, workflowCol, dateCol);

            primaryStage.show();
        }
    }

    import javafx.beans.property.SimpleStringProperty;

    public class TblQuery {

        private final SimpleStringProperty idProperty = new SimpleStringProperty();
        private final SimpleStringProperty workflowProperty = new SimpleStringProperty();
        private final SimpleStringProperty dateProperty = new SimpleStringProperty();

        public TblQuery(String id, String workflow, String date) {
            this.idProperty.set(id);
            this.workflowProperty.set(workflow);
            this.dateProperty.set(date);
        }

        public void setId(String id) {
            this.idProperty.set(id);
        }

        public String getId() {
            return idProperty.get();
        }

        public String getWorkflow() {
            return workflowProperty.get();
        }

        public void setWorkflow(String workflow) {
            this.workflowProperty.set(workflow);
        }

        public String getDate() {
            return dateProperty.get();
        }

        public void setDate(String date) {
            this.dateProperty.set(date);
        }
    }
