Pass inputs to nested component in Angular 2

I’m not sure if I got it right but here is my implementation ( PLUNKER )

const FIRST_PARTY_OWN_INPUTS = ['not', 'passthrough'];
const FIRST_PARTY_PASSTHROUGH_INPUTS = ['all', 'attrs', 'are', 'passed'];

const generateAttributes(arr) {
   return arr.map(att => '[' + att + '] = "' + att + '"').join(' ');
}


//-------------------------------------------------------//////////////////
import {Component} from '@angular/core'

@Component({
  selector: 'third-party',
  inputs: [...FIRST_PARTY_PASSTHROUGH_INPUTS],
  template: `
<div>
  {{all}} , {{attrs}} ,  {{are}} ,  {{passed}}
</div>
  `
})
export class ThirdParty {
}

@Component({
  selector: 'first-party',
  inputs: [...FIRST_PARTY_OWN_INPUTS, ...FIRST_PARTY_PASSTHROUGH_INPUTS],
  template: `
<div>
  <div>
    {{not}} , {{passthrough}}
  </div>
  <third-party ${generateAttributes(FIRST_PARTY_PASSTHROUGH_INPUTS)}></third-party>
  <first-party-extra></first-party-extra>
</div>
  `,
  directives: [ThirdParty]
})
export class FirstParty {
}

@Component({
  selector: 'my-app',
  providers: [],
  template: `
    <div>
      <h2>Hello {{name}}</h2>
      <first-party [not]="'not'" [passthrough]="'passthrough'"  
                   [all]="'all'" [attrs]="'attrs'" [are]="'are'" [passed]="'passed'">
      </first-party>
    </div>
  `,
  directives: [FirstParty]
})
export class App {
  constructor() {
    this.name="Angular2 (Release Candidate!)"
  }
}

Hope it helps :)
