Javafx with Scene builder - Update ListView items after adding list item

Question

How do i update ListView items when i added a new data. Here is my code for displaying data to my listview:

public class ChapterController implements Initializable {

@FXML
private ListView<String> listview;
ObservableList<String> view = FXCollections.observableArrayList();

@FXML
private TextField des;
@FXML
private TextField no;

Connection connection = null;
PreparedStatement preparedStatement = null;
ResultSet resultSet = null;

public ChapterController() {
connection = Connect.ConnectDb();
}
@Override
public void initialize(URL url, ResourceBundle rb) {
    listview.setItems(view);
    ListView()
}  

//display data to the listview
private void ListView(){
    String sql = "SELECT * FROM chapter ORDER BY id ASC";
    try{
        preparedStatement = connection.prepareStatement(sql);
        resultSet = preparedStatement.executeQuery();

        while(resultSet.next()){
              view.add("Chapter" +" "+ resultSet.getString(1) +" "+ "-" +" "+ resultSet.getString(2));
        }
    }catch(Exception e){

    }
}

And here is my code for adding item on the list view, and I want to automatically updated the listview when I save the data. Where should I put my code for updating the listview.

public void buttonAction(ActionEvent event){
    connection = Connect.ConnectDb();
    try{
        String sql = "INSERT INTO chapter"
            +"(id, description)"
               +"VALUES(?,?)";

        preparedStatement = (PreparedStatement) connection.prepareStatement(sql);
        preparedStatement.setString(1, no.getText());
        preparedStatement.setString(2, des.getText());
        preparedStatement.executeUpdate();
        ListView();  //I am using to call the ListView but it is not good at all
    }catch(Exception e){

    }
}
