title: Loading state button in Bootstrap 3
body: <p>I'm new to Bootstrap 3. Can't figure out how to activate the loading state button function. My code below is from the documents on <a href="http://getbootstrap.com" rel="noreferrer">getboostrap.com</a>.</p>
  
  <pre><code>&lt;button type="button" data-loading-text="Loading..." class="btn btn-primary"&gt;
    Loading state
  &lt;/button&gt;
  </code></pre>
  
  <p>Dropdowns works fine so I guess the problem is somewhere else? </p>
