title: add class to next and previous div in carousel
body: <p>I'm using <a href="http://kenwheeler.github.io/slick/" rel="nofollow">Slick</a> and I'm trying to add classes to the next and previous slides in my carousel. The active slide has the class slick-active, so I used this:</p>
  
  <pre><code>$(".slick-active").prev().addClass('prevdiv');
  $(".slick-active").next().addClass('nextdiv');
  </code></pre>
  
  <p>But the problem is that if I go to the next slide, the classes don't move. I've been trying to look for solutions, and saw something about using trigger &amp; bind maybe?</p>
  
  <p>Fiddle: <a href="http://jsfiddle.net/ak9Lnrjj/1/" rel="nofollow">http://jsfiddle.net/ak9Lnrjj/1/</a> (I made it focus on select, so click on the next or previous slide to make that slide active).</p>
