title: Get selected options from from ajax-chosen plugin
body: <p>I am trying to figure out how to get selected options from <a href="https://github.com/meltingice/ajax-chosen" rel="nofollow">ajax-Chosen</a> plugin with no luck.</p>
  
  <p>This is my html: </p>
  
  <pre><code>&lt;select multiple='multiple' class='chzn-select' data-placeholder='users'&gt;
    &lt;option value='0' selected&gt;username1&lt;/option&gt;
    &lt;option value='1' selected&gt;username2&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>And this is JS part:</p>
  
  <pre><code>$(".chzn-select").ajaxChosen({
    method: 'GET',
    url: 'users.php',
    dataType: 'json',
    minTermLength: 3,
    afterTypeDelay: 300
  }, function (data) {
    var terms = {};
  
    $.each(data, function (i, val) {
       terms[i] = val;
    });
  
    return terms;
  });
  </code></pre>
  
  <p>This all works fine. But when I remove one option "username2" the select field does not get updated. So when I want to get all selected users from list I get wrong list - in this case I always get both values even that one was removed from list.</p>
  
  <p>I've also tried to trigger update with no luck:</p>
  
  <pre><code>$(".chzn-select").trigger("liszt:updated");
  </code></pre>
  
  <p>Does anyone have a suggestion how to get real values from select list?</p>
