title: Angular UI.Bootstrap's radio buttons act strange with ng-repeat
body: <p>I have a problem dynamically generating options for a radio model in angular's ui.bootstrap. I thought I could simply ng-repeat over an array, using it's contents for the btn-radio attribute like so:</p>
  
  <pre><code>//in the controller
  $scope.radioModel =  undefined;
  $scope.radioModelButtons = ["a", "b", "c"];
  
  //in the html
  &lt;div class="btn-group" &gt;
    &lt;button ng-repeat="value in radioModelButtons"
      class="btn" type="button" ng-model="radioModel"
      btn-radio="'{{value}}'"&gt;
        {{value}}
    &lt;/button&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I'm using angular 1.1.4 and ui.bootstrap 0.3.0.</p>
  
  <p><a href="http://jsfiddle.net/yMLqz/">Here is a jsfiddle of my efforts</a>, as you can see, the radio buttons act independently and do not affect the radioModel variable.</p>
  
  <p>Thanks!</p>
