title: Tag-It Autocomplete doesn't trigger list on focus
body: <p>I have this Tag-it plugin up and running with just a flaw that I must correct.</p>
  
  <p>It doesnt't show the list of tags when the mouse enters the input field, even with the <code>showAutocompleteOnFocus:true,</code> property.</p>
  
  <p>So far I have this code</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
          $(document).ready(function() {
              $("#categories").tagit({
                  fieldName: "categories[]",
                  availableTags: &lt;?php echo $categories; ?&gt;,
                  showAutocompleteOnFocus:true,
                  allowSpaces:true
  
              });
          });
  &lt;/script&gt;
  
  &lt;ul id="categories"&gt;&lt;ul&gt;
  </code></pre>
  
  <p>The Categories echo renders like this</p>
  
  <pre><code>["Categoria","Categoria 2","Categoria 3","Promoção"]
  </code></pre>
  
  <p>Any help would be much appreciated!</p>
  
  <p>Thanks in advance!</p>
