title: Detect when slick slider initialises
body: <p>I'm trying to fire some code when <a href="http://kenwheeler.github.io/slick/" rel="noreferrer">slick</a> initializes. Apparently in the newest version 1.4 "callback methods have been deprecated and replaced with events."</p>
  
  <p>This doesn't work for me though:</p>
  
  <pre><code>$('.spv-slider').on('init', function(event, slick){
      console.log("initialised")
  });
  </code></pre>
  
  <p>what's wrong with it?</p>
