title: Selectize.js delegated event on option not working
body: <p>I'm currently trying to listen to click events on generated options inside the dropdown, but I'm currently unable to achieve this.</p>
  
  <p>Since options aren't generated when the DOM loads, I'm delegating the event to the document listening for clicks on the dropdown's options. My code currently looks like this:</p>
  
  <pre><code>var $accountsSelectize = $('#accounts-input').selectize({
    ...
  });
  
  $(document).on('click', '.accounts-input-selectize .option', function(event) {
    alert('An option was clicked!');
  });
  </code></pre>
  
  <p>But this doesn't seem to be working. Any idea on why this is happening? Any clue regarding why this event isn't firing at all will be more than welcome.</p>
  
  <p>Edit: Just an FYI, I'm adding a class to the HTML input element, that's why I'm listening for clicks on <code>.accounts-input-selectize .option</code>:</p>
  
  <pre><code>&lt;input type="text" id="accounts-input" class="accounts-input-selectize" placeholder="Search accounts"&gt;
  </code></pre>
