title: Bootstrap Multiselect plugin filter uppercase
body: <p>I'm working on Bootstrap Multiselect, and I'm using bootstrap 3.1, and downloaded <a href="http://davidstutz.de/bootstrap-multiselect/" rel="nofollow noreferrer">this script</a></p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      $(document).ready(function() {
          $('#example28').multiselect({
              includeSelectAllOption: true,
              enableFiltering: true,
              maxHeight: 150
          });
      });
  &lt;/script&gt;
  
  &lt;select id="example28" multiple="multiple"&gt;
    &lt;option value="cheese"&gt;Ahmet Burak&lt;/option&gt;
    &lt;option value="tomatoes"&gt;Tomatoes&lt;/option&gt;
    &lt;option value="mozarella"&gt;Mozzarella&lt;/option&gt;
    &lt;option value="mushrooms"&gt;Mushrooms&lt;/option&gt;
    &lt;option value="pepperoni"&gt;Pepperoni&lt;/option&gt;
    &lt;option value="onions"&gt;Onions&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I tried many times to use filter. If I don't use first char uppercase in form, it doesn't find anything. How can I solve it?</p>
