Angular2 Bootstrap component with input values

Question

How can I pass input values to a component that needs to be bootstrapped in angular2

At the time of bootstrap, how can I pass some value to sampleInput?

@NgModule({
  declarations: [SampleComponent],
  imports     : [],
  exports     : [],
  providers   : [
  ],  bootstrap   : [SampleComponent]
})
export class  WrapperAppModule {

}

and my SampleComponent code is,

@Component({
  selector   : 'app-sample',
  styleUrls: ['./app.sample.css'],
  template: `<div>sample app</div>`,
})
export class SampleComponent {

@Input('sampleInput') sampleInput:string;
}
