OnPush works when input referense changed

input.ts

@Component({
  selector: 'child',
  template: `
    <h1>{{object.name}}</h1>
    {{runChangeDetection}}
  `,
  changeDetection: ChangeDetectionStrategy.OnPush
})
export class TooltipComponent {
  @Input() object;
  get runChangeDetection() {
    console.log('Checking the view');
    return true;
  }
}

@Component({
  selector: 'app-root',
  template: `
    <child [object]="object"></child>
    <button (click)="onClick()">Click</button>
  `
})
export class AppComponent {
  object = {
    name: 'Angular'
  };

  onClick() {
    this.object.name = 'React';
  }
}
