title: Bootstrap radio-buttons toggle issue
body: <p>I'm trying to turn some regular buttons in radio buttons the twitter bootstrap way (<a href="http://twitter.github.com/bootstrap/javascript.html#buttons">http://twitter.github.com/bootstrap/javascript.html#buttons</a>).</p>
  
  <p>I followed the instructions, but when I press the buttons I get the following error in the console:</p>
  
  <p><strong>Uncaught Error: cannot call methods on button prior to initialization; attempted to call method 'toggle'</strong> .</p>
  
  <p>Do you know what might cause it? The buttons are loaded in the page and only become visible when the corresponding content is displayed by AJAX.</p>
  
  <p>Thanks!</p>
