Is this notice "Identifier 'gridOptions' refers to a private member of the componentAngular" telling me that I am not following coding best practices?

Question

I am using ag-grid as a framework to build my grids(OBVIOUSLY).
I have followed a simple tutorial. So here's the code so far,

typography.component.html

typography.component.ts

import {Component} from "@angular/core";
import {GridOptions} from "ag-grid-community";


@Component({
    selector: 'typography-cmp',
    moduleId: module.id,
    templateUrl: 'typography.component.html'
})

export class TypographyComponent {
    private gridOptions: GridOptions;

    constructor() {
        this.gridOptions = <GridOptions>{};
        this.gridOptions.columnDefs = [
            {
                headerName: "ID",
                field: "id",
                width: 100
            },
            {
                headerName: "Value",
                field: "value",
                width: 100
            },

        ];
        this.gridOptions.rowData = [
            {id: 5, value: 10},
            {id: 10, value: 15},
            {id: 15, value: 20}
        ]
    }
}  

This works perfecly. However, as you may have noticed in the html file:

gridOptions

is underlied in red. And this is why:

Identifier 'gridOptions' refers to a private member of the component

That is understandable. I am following the official tutorial. And I am wondering whether the code breaks any coding rules or best practices?
Thank you.

As you are using gridOptions in your template, it should not be declared as private variable.

More reference on this: Angular2 - should private variables be accessible in the template?
