title: ng-selected not working with ng-options or ng-repeat
body: <p>I have a form which the user can fill out to get directions to a destination using google maps.
  There are 350 possible set destinations that the user can chose from. They can chose this destination by clicking on a pin on the google map or else from a select menu in the form.</p>
  
  <p>When they click on the pin on the google map I would like the select menu to change to the destination. </p>
  
  <p>I am trying to use ng-selected for this however it isn't working.</p>
  
  <p>Any help would be grately appreciated. Thank you.</p>
  
  <h1>View</h1>
  
  <pre><code>   &lt;div id="select_destination"&gt;
          &lt;select data-ng-model="selectedDestination" 
                  ng-options="station.stationID as station.stationShortAddress for station in allStationsMapData track by station.stationID" 
                  data-ng-change="selectDestination(selectedDestination)"
                  ng-selected="station.stationID == selectedDestination"&gt;
          &lt;/select&gt;
      &lt;/div&gt;
  </code></pre>
  
  <h1>Controller</h1>
  
  <p>A function called getDirections is called when a user clicks on a station on the map (not selecting from the select menu). This should change the currently selected item of the select menu but doesn't. (Note: the function is executing correctly passing in the right stationID.)</p>
  
  <pre><code>$scope.getDirections = function(stationLat, stationLng, stationID){ 
      //update the select menu model to the chosen stationID.
      $scope.selectedDestination = stationID;     
  };
  </code></pre>

  <p>I also tried using ng-selected with ng-repeat however it didn't work either.</p>
  
  <pre><code>&lt;select data-ng-model="selectedDestination" data-ng-change="selectDestination(selectedDestination)"&gt;
      &lt;option ng-repeat="stationMapData in allStationsMapData" 
          value="{{stationMapData.stationID}}" 
          ng-selected="{{stationMapData.stationID == selectedDestination}}"&gt;
          {{stationMapData.stationShortAddress}}
      &lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
