title: angularjs button event not firing when clicked
body: <p>I'm missing something here in the wiring. When the button is clicked the alert in the method isn't displayed.</p>
  
  <pre><code>  &lt;div id="mapFilter" ng-controller="MapsController"&gt;
     &lt;div&gt;
       &lt;h3&gt;{{SelectedCustomer.officeName}}&lt;/h3&gt;
       &lt;input type="button" ng-click="getProperties()" value="Get Data" /&gt;
     &lt;/div&gt;
  
     &lt;div&gt;
       &lt;p&gt;hotel count: {{allHotels.length}}&lt;/p&gt;
       &lt;p&gt;preferred count: {{preferredHotels.length}}&lt;/p&gt;
     &lt;/div&gt;
   &lt;/div&gt;
  </code></pre>
  
  <p>The expected execution point:</p>
  
  <pre><code>    $scope.getProperties =  function () {
      var msg = 'Unable to load Properties: ';
  
      alert("getProperties");
  </code></pre>
