title: Angular UI Select, undefined ng-model
body: <p>I have below code from example of Angular UI Select:</p>
  
  <pre><code>&lt;ui-select multiple ng-model="SelectedItem" style="width: 300px;"&gt;
      &lt;ui-select-match placeholder="Select colors"&gt;{{$item}}&lt;/ui-select-match&gt;
      &lt;ui-select-choices repeat="color in availableColors"&gt;{{color}} Cool&lt;/ui-select-choices&gt;
  &lt;/ui-select&gt;
  &lt;p&gt;Selected: {{SelectedItem}}&lt;/p&gt;
  </code></pre>
  
  <p>And nd-model didnt define any scope variable. <code>&lt;p&gt;</code> show only 'Selected: ' and in controller variable $scope.SelectedItem is undefined. The rest is working fine.</p>
