title: AngularJS dropdown list loses content after item selected
body: <p>I have an ASP.Net WebAPI project that I run from VS that supplies data in the form of JSON to my Angular project. I get the data from the webapi via an $http.get call like so:</p>
  
  <pre><code>function CarController($scope, $http) {
      $http.get('http://localhost:1246/api/values')
           .success(function (data, status, headers, config) {
               $scope.carSet = data;
           })
           .error(function (data, status, headers, config) {
               $scope.error = status;
               alert("You be broken buddy!");
           });
  }
  </code></pre>
  
  <p>Then the carSet is bound in the html like this:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html data-ng-app=""&gt;
  &lt;head&gt;
      &lt;title&gt;&lt;/title&gt;
      &lt;script src="scripts/controllers/controller.js"&gt;&lt;/script&gt;
      &lt;script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.1/angular.min.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;div data-ng-controller="CarController"&gt;
          &lt;select data-ng-model="carSet" onchange="DataChanged()" data-ng-options="c.Color for c in carSet"&gt;&lt;/select&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Everything works great. I get my list. The first entry is blank and that is ok for now.  </p>
  
  <p>THE PROBLEM:<br>
  When I select any of the items in the dropdown list, the entire list is cleared out and there are no more items to select from?? Whaaaaat! At this point I am clearly frustrated.  This behavior only happens when I use the $http mechanism to retrieve data from the WebApi.  It does not happen if I use the $http.get to retrieve json data from a file or other locally created data stores.  I just need a simple dropdown list that will allow me to use it's selected values for filtering other data (another db call.)</p>
  
  <p>I would show you pics.. but this is my very first post.. and well.... I can't.</p>
  
  <p>Any help is greatly appreciated.  Thanks.</p>
