title: Nativescript radListView do not show Item
body: <h1><strong>Overview</strong></h1>
  <p>Nativescript radListView does not show bind item from component on both  ios and android os. <br>
  Action bar and usual ListView shows data but radlistview do not.
  Console shows no error.
  But I saw RadListView from next repository can work -&gt; <a href="https://github.com/telerik/nativescript-ui-samples-angular" rel="nofollow noreferrer">https://github.com/telerik/nativescript-ui-samples-angular</a></p>
  <h1><strong>Environment</strong></h1>
  <p>My development environment is below.</p>
  <p>os: macOS sierra 10.12.6 <br>
  node : v6.12.0 <br>
  npm : 3.10.10 <br>
  nativescript and others can be seen after, at package.json</p>
  <h1><strong>Consideration</strong></h1>
  <p>I seems this problem is about these... <br>
  but I can not refine.</p>
  <ol>
  <li>angular directive <br></li>
  <li>initializing an observable array <br></li>
  </ol>
  <h1><strong>Code</strong></h1>
  <p>I implemented RadListView on angular like below just after 'tns create ui-test --ng'.</p>
  <p><strong>Component</strong></p>
  <pre><code>export class ItemsComponent implements OnInit {
      private _dataItems: ObservableArray&lt;Item&gt;;
  
      constructor() {
      }
  
      get dataItems(): ObservableArray&lt;Item&gt; {
          return this._dataItems;
      }
  
      ngOnInit() {
          this._dataItems = new ObservableArray([
              { id: 1, name: &quot;Ter Stegen&quot;, role: &quot;Goalkeeper&quot; },
              { id: 3, name: &quot;Piqué&quot;, role: &quot;Defender&quot; },
              { id: 4, name: &quot;I. Rakitic&quot;, role: &quot;Midfielder&quot; }
          ]);
      }
  }
  </code></pre>
  <p><strong>html</strong></p>
  <pre><code>&lt;ActionBar title=&quot;My App&quot; class=&quot;action-bar&quot;&gt;
  &lt;/ActionBar&gt;
  
  &lt;GridLayout&gt;
      &lt;RadListView [items]=&quot;dataItems&quot;&gt;
          &lt;ng-template let-item=&quot;item&quot;&gt;
              &lt;StackLayout&gt;
                  &lt;Label class=&quot;nameLabel&quot; text=&quot;text&quot;&gt;&lt;/Label&gt;
                  &lt;Label class=&quot;nameLabel&quot; [text]=&quot;item.name&quot;&gt;&lt;/Label&gt;
                  &lt;Label class=&quot;descriptionLabel&quot; [text]=&quot;item.role&quot;&gt;&lt;/Label&gt;
              &lt;/StackLayout&gt;
          &lt;/ng-template&gt;
      &lt;/RadListView&gt;
  &lt;/GridLayout&gt;
