title: Angular Slick slickGoTo doesn't work
body: <p>I'm using <a href="https://github.com/devmark/angular-slick-carousel" rel="nofollow">angular-slick-carousel</a>. The problem is Slick methods doesn't work, for example <code>slickGoTo()</code> .  </p>
  
  <p>This is my Controller as in the documentation :</p>
  
  <pre><code>$scope.slickConfig = {
     method: {}
  };
  </code></pre>
  
  <p>And my view: </p>
  
  <pre><code>&lt;slick infinite=true
          arrows=true
          speed=500
          slides-to-show=4
          slides-to-scroll=1
          as-nav-for=".slider-for"
          class="slider-nav"
          settings="slickConfig"
          &gt;
  
      &lt;a  href=""
          class="thumb col-xs-2"
          ng-repeat="photo in photos"
          ng-click="slickConfig.method.slickGoTo(2)"&gt; // &lt;&lt;&lt;&lt; method doesn't work
  
          &lt;img ng-src="{{photo.thumb}}" alt=""&gt;
  
      &lt;/a&gt;
  
  &lt;/slick&gt;
  </code></pre>
  
  <p><strong>Maybe I'm using it WRONG?</strong></p>
