title: Ionic/Angular retrieve selected radio in a list
body: <p>I am using Ionic and I'm having a hard time retrieving selected radio buttons.</p>
  
  <p>The following is my HTML</p>
  
  <pre><code>&lt;div class="list"&gt;
    &lt;label class="item item-radio"&gt;
      &lt;input type="radio" name="group" ng-model="answer"&gt;
        &lt;div class="item-content"&gt;
          Canada
        &lt;/div&gt;
      &lt;i class="radio-icon ion-checkmark"&gt;&lt;/i&gt;
    &lt;/label&gt;
    &lt;label class="item item-radio"&gt;
      &lt;input type="radio" name="group" ng-model="answer"&gt;
        &lt;div class="item-content"&gt;
          Africa
        &lt;/div&gt;
      &lt;i class="radio-icon ion-checkmark"&gt;&lt;/i&gt;
    &lt;/label&gt;
    &lt;label class="item item-radio"&gt;
      &lt;input type="radio" name="group" ng-model="answer"&gt;
        &lt;div class="item-content"&gt;
          North America
        &lt;/div&gt;
      &lt;i class="radio-icon ion-checkmark"&gt;&lt;/i&gt;
    &lt;/label&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Any suggestions on how to approach that issue? Is there a way to access the model object from $scope after having selected the answer?</p>
