title: Ionic 2 navigation pages dont work
body: <p>I have problem with my first ionic 2 app just doing a tutorial form official blog of ionic and this just dont work for me, this is my home.ts</p>
  
  <pre><code>import {Page} from 'ionic-angular';
  import {AboutPage} from '../about/about';
  
  @Page({
    templateUrl: 'build/pages/home/home.html'
  })
  export class HomePage {
    aboutPage = AboutPage;
  
    constructor() {
    this.name = "Bartek";
    }
  }
  </code></pre>
  
  <p>and this is my home.html and this should just navigate me to next page:</p>
  
  <pre><code>&lt;ion-navbar *navbar&gt;
  
  
  &lt;ion-title&gt;
      Hello World
    &lt;/ion-title&gt;
  &lt;/ion-navbar&gt;
  
  &lt;ion-content class="home"&gt;
    &lt;ion-card&gt;
      &lt;ion-card-header&gt;
        Card Header
      &lt;/ion-card-header&gt;
      &lt;ion-card-content&gt;
        Hello
        &lt;button [navPush]="aboutPage"&gt;Go To About&lt;/button&gt;
      &lt;/ion-card-content&gt;
