NG0100: Expression has changed after it was checked

[zakarea-Tfaili]

I am using ng-select2 inside a helper controller

export class DropdownInputComponent implements ControlValueAccessor, OnInit {
@input() data: Array;
.
.
.
constructor(@self() public ngControl: NgControl, private elementRef: ElementRef) {
this.ngControl.valueAccessor = this;
}
.
.
.

}

when adding [formControl]="ngControl.control" to the ng-select2 component and the data is returned by
this.structureService.getAvailableStructures().subscribe(response => {
this.structures = response;
});

An error ExpressionChangedAfterItHasBeenCheckedError is thrown
