title: twitter-bootstrap buttons javascript doesnt work
body: <p>I have a control-group with a button group as checkboxes like this : </p>
  
  <pre><code>&lt;div class="control-group" id="cyb3r" &gt;
              &lt;label class="control-label" for="c"&gt;C&lt;/label&gt;
              &lt;div class="btn-group navs controls" data-toggle="buttons-checkbox"&gt;
                  &lt;button class="btn" type="button"&gt;1&lt;/button&gt;
                  &lt;button class="btn" type="button"&gt;2&lt;/button&gt;
                  &lt;button class="btn" type="button"&gt;3&lt;/button&gt;
              &lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>and I include these :</p>
  
  <pre><code>&lt;link rel="stylesheet"
      href="&lt;?php echo base_url('assets/style/style.css');?&gt;"&gt;
  &lt;link rel="stylesheet"
      href="&lt;?php echo base_url('assets/style/bootstrap.min.css');?&gt;"&gt;
  &lt;script
      type="text/javascript"
      src="&lt;?php echo base_url('assets/script/jquery.js')?&gt;"&gt;&lt;/script&gt;
  &lt;script
      type="text/javascript"
      src="&lt;?php echo base_url('assets/script/bootstrap.min.js')?&gt;"&gt;&lt;/script&gt;
  &lt;script
      type="text/javascript"
      src="&lt;?php echo base_url('assets/script/bootstrap-button.js')?&gt;"&gt;
      &lt;/script&gt;
  &lt;script
      type="text/javascript"
      src="&lt;?php echo base_url('assets/script/js.js')?&gt;"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>and js.js :</p>
  
  <pre><code>$(function(){
      $('#cyb3r').button();  
  });
  </code></pre>
  
  <p>I tried these also :</p>
  
  <pre><code>$(function(){
      $('.navs').button();  
  });
  
  $(function(){
      $('.control-group').button();  
  });
  </code></pre>
  
  <p>but none of them work for that checkbox group.
  but why?</p>
