title: Typescript method not called
body: <p>I have an Import/Export functionality.</p>
  
  <p>Here is my cshtml code.</p>
  
  <pre><code>&lt;a href="#" onclick="$('#importPopup').dialog('open');return false;"&gt;&lt;img src="import.png" class="btn btn-default btn-xs" title="Importfrom file" data-toggle="tooltip" data-placement="bottom" /&gt;&lt;/a&gt;
  
  &lt;a href="#" onclick="return false;" ng-click="myViewModel.ExportFile()"&gt;&lt;img src="export.png" class="btn btn-default btn-xs" title="Export to file" data-toggle="tooltip" data-placement="bottom" /&gt;&lt;/a&gt;
  
  &lt;div id="importPopup" title="Import"&gt;
      &lt;p&gt;&lt;input type="file" id="file_upload" name="file_upload" /&gt;&lt;/p&gt;
      &lt;p&gt;&lt;input type="button" class="_button" value="Import File" ng-click="myViewModel.ImportFile()" /&gt;&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Now I have two functions on my typescript code.</p>
  
  <pre><code>public ImportFile() {
      // some codes here
  }
  
  public ExportFile() {
      // some codes here
  }
  </code></pre>
  
  <p>My problem here is my <code>ImportFile</code> function is not being hit. I tried to put two breakpoints on both of them, and the <code>ExportFile</code> is working but not the <code>ImportFile</code>.</p>
  
  <p>What did I missed here?</p>
