title: uikit 3 catch events
body: <p>I use uikit v3 and I'm trying to log clicks in a uikit lightbox/slideshow. After the event "itemshow" I would like to send a log request to piwik. The piwik request is not the problem, but i'm not able to catch the event "itemshow".

  <pre><code>$(function () {
          $("div.uk-lightbox").on('itemshow', function() {
              alert("it works"); // it does not...
          });
      });
  </code></pre>
