title: Bootstrap btn-group doesn't change radio buttons
body: <p>So here is my markup</p>
  
  <pre><code>      &lt;div class="btn-group" data-toggle="buttons"&gt;
      &lt;label class="btn btn-primary"&gt;
          &lt;input type="radio" name="account-type" id="optionsRadios1" value="1"&gt; &lt;span class="glyphicon glyphicon-user"&gt;&lt;/span&gt;
  User&lt;/label&gt;
      &lt;label class="btn btn-primary active"&gt;
          &lt;input type="radio" name="account-type" id="optionsRadios2" value="2" checked&gt; &lt;span class="glyphicon glyphicon-eye-open"&gt;&lt;/span&gt;
  Special user&lt;/label&gt;
      &lt;label class="btn btn-primary"&gt;
          &lt;input type="radio" name="account-type" id="optionsRadios2" value="3"&gt; &lt;span class="glyphicon glyphicon-home"&gt;&lt;/span&gt;
  Agency&lt;/label&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>It renders everything fine, the problem is that if I select value 3, it won't mark the third radio buttons as checked, or any other options if I select it, so when I submit the form, it doesn't matter which option I choose, the option that is checked by default, that will be submitted.</p>
  
  <p>Any tips?</p>
