Angular 2 – 2 Way Binding with NgModel in NgFor

After digging around I need to use trackBy on ngFor. Updated plnkr and code below. Hope this helps others.

Working Plnkr

@Component({
  selector: 'my-app',
  template: `
  <div>
    <div *ngFor="let item of toDos;let index = index;trackBy:trackByIndex;">
      <input [(ngModel)]="toDos[index]" placeholder="item">
    </div>
    Below Should be binded to above input box
    <div *ngFor="let item of toDos">
      <label>{{item}}</label>
    </div>
  </div>
  `,
  directives: [MdButton, MdInput]
})
export class AppComponent { 
  toDos: string[] =["Todo1","Todo2","Todo3"];
  constructor() {}
  ngOnInit() {
  }
  trackByIndex(index: number, obj: any): any {
    return index;
  }
}
