title: WinJS.UI.ListView items not displayd
body: <p>Trying to display a sorted list in a div. But I get only an empty div.</p>
  
  <p>HTML   </p>
  
  <pre><code>&lt;div id="contentDmChat" data-win-control="WinJS.UI.ListView"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>JS-Code:</p>
  
  <pre><code>contentDmChat.itemTemplate = myTemplate;
  contentDmChat.layout = WinJS.UI.ListLayout;
  contentDmChat.tapBehavior = 'directSelect';
  contentDmChat.selectionMode = 'single';
  contentDmChat.itemDataSource = userMs;
  </code></pre>
  
  <p>List for data source has elements. 
  Any idea?</p>
