call a method from an inner Method

Question

I'm using ag-grid and reacting to some events I want to access to methods defined in the current componnet something like this:

@Component({
  selector: 'whatever',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit, OnDestroy{

...

methodToCall(params : any){
  return 1;
}


gridOptions = {

  onCellValueChanged: function(params : DynamicComponentParams){  
       *//I want from here to call the method "methodToCall"*
       this.methodToCall(null); *//this doesn't work....*

  },


 ..... 

};

So from the method: "onCellValueChanged" I need to call the method "methodToCall", using this here is wrong because the scope is different, but then How do I can accomplish that?

Try arrow function => like this -

onCellValueChanged = (params : DynamicComponentParams): void => {  
       *//I want from here to call the method "methodToCall"*
       this.methodToCall(null); *//this doesn't work....*

  },

@navy1978 Change the colon after the method name to an equals sign. – The Head Rush Feb 13 '19 at 13:16
