@> operator

@Component({
  selector: '...',
  viewProviders: [...],
  templateUrl: '...',
  directives: [...],
    providers: [...]
})
export class TestComponent {
  new google.visualization.Query('...')
     .send((response : any)=> {
        let datatable = response.getDataTable();
        ...
        results.push(item);
      }

      this.viewCollection = results; //this will refer to the TestComponent
    });
...
}
