title: bootstrap-select nothing selected
body: <p>I am using bootstrap select.</p>
  
  <pre><code>&lt;select name="categories[]" id="cat" class="selectpicker" multiple&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>and getting the option tag from here,</p>
  
  <pre><code>var result='';
  for(var i=0;  i&lt;res.getcategories.length;  i++) 
  {                    
    result += '&lt;option value='+res.getcategories[i].cat_id+'&gt;'+res.getcategories[i].category+'&lt;/option&gt;';                 
     $('#cat').html(result); 
  
  }
  </code></pre>
  
  <p>However it always displays Nothing selected and i donot display other options. If i donot use bootstap class 'selectpicker' everything is fine.</p>
