title: Bootstrap radio button group not marking radios as checked
body: <p>I'm having a few issues with Bootstrap 3 radio button groups.</p>
  
  <p>When I select the radio button, it is not marking the radio button as checked, it is only adding 'active' to the radio label.</p>
  
  <p>So when I try and pull the checked radio button via PHP and Codeigniter specifically there are no values.</p>
  
  <p>Should the radio buttons not work as a normal radio button should?</p>
  
  <p>Here's the radio button code</p>
  
  <pre><code>&lt;div class="form-group"&gt;
      &lt;label for="Custom Branding"&gt;Custom Branding&lt;/label&gt;&lt;br /&gt;
      &lt;div class="btn-group user_toggle" data-toggle="buttons"&gt;
          &lt;label class="btn btn-default btn-sm active"&gt;
              &lt;input type="radio" name="default_branding" value="0" autocomplete="off" &gt; No
          &lt;/label&gt;
          &lt;label class="btn btn-default btn-sm"&gt;
              &lt;input type="radio" name="default_branding" value="1" autocomplete="off"&gt; Yes
          &lt;/label&gt;
      &lt;/div&gt;  
  &lt;/div&gt;
  </code></pre>
  
  <p>So when I click a radio button, neither of the radio buttons are marked as checked.</p>
  
  <p>And the radio buttons are only in the POST array if a change has been made, but I need all the values there.</p>
  
  <p>What am i doing wrong?      </p>
