title: paper-radio-group buttons inside a template possible?
body: <p>I'm creating a project with Polymer and have the following code:</p>
  
  <pre><code>&lt;paper-radio-group&gt;
      &lt;template repeat="{{answer in answers}}"&gt;
          &lt;p&gt;
              &lt;paper-radio-button name="{{answer.choice}}" label="{{answer.choice}}"&gt;&lt;/paper-radio-button&gt;
          &lt;/p&gt;
      &lt;/template&gt;
  &lt;/paper-radio-group&gt;
  </code></pre>
  
  <p>I have a list of answers that I want to use in the paper-radio-group. Displaying this works fine. Every item in the answers array is displayed as a paper-radio-button. </p>
  
  <p>The problem is that they are not connected to each other. So, when selecting one paper-radio-button, another is not deselected. This is probably because the paper-radio-group tag is outside the template tag. But placing it inside would make it repeat like the paper-radio-button and that's not going to work either.</p>
  
  <p>Is there a way to get this to work? Or is it not possible?</p>
