title: Error iteration with ng-options
body: <p>I have an array of objects, describing seats.<br>
  each seat object looks like this:</p>
  
  <pre><code>ID: 1
  platz: 1
  status: 1
  title: "Sitzplatz #1"
  userID: 1
  </code></pre>
  
  <p>now I used AngularJS with ng-options to iterate over my object array like this:</p>
  
  <pre><code>&lt;select ng-options="s.status for s in seating"&gt;&lt;/select&gt;
  </code></pre>
  
  <p>but i got an error:</p>
  
  <pre><code>Error: [$compile:ctreq] http://errors.angularjs.org/1.5.0/$compile/ctreq?p0=ngModel&amp;p1=ngOptions
