title: Angular ng-change for select not calling the declared method
body: <p>I have the following html form select statement</p>
  
  <pre><code>&lt;select ng-change="setBillGroup()" ng-model="bill.groupId" class="span8" ng-options="d.id as d.name for d in groups"&gt;&lt;/select&gt;
  </code></pre>
  
  <p>and the js</p>
  
  <pre><code>myApp.controller('myAppController', function($scope, myAppService) {
  
  .....
  function setBillGroup(){
   console.log("setBillGroup method called!");
      ......
   }
  
  ....
  });
  </code></pre>
  
  <p>But for some reason the setBillGroup() never seems to get called when I select something or the other in the form.</p>
