title: Angulartics doesn't track my events on buttons or links
body: <p>I've followed the "tutorial" on Angulartics' website and ended up with this event code on my buttons and links:</p>
  
  <p><strong>Buttons</strong></p>
  
  <pre><code>&lt;button class="btn btn-default" ng-controller="ctrl" ng-click="openModal()" analytics-on="click" analytics-event="button" analytics-categori="Main page" analytics-label="Modal bottom"&gt;Open modal!&lt;/button&gt;
  </code></pre>
  
  <p><strong>Links</strong></p>
  
  <pre><code>&lt;a ui-sref="ui.state" data-toggle="collapse" data-target="#navbar" analytics-on="click" analytics-event="button" analytics-categori="Header" analytics-label="FAQ"&gt;FAQ&lt;/a&gt;
  </code></pre>
  
  <p>I have injected both <em>angulartics</em> and <em>angulartics.google.analytics</em> to my app and it works as it should, no errors anywhere. I have deleted the <em>ga('send', 'pageview')</em> from the Google Analytics code-snippet.</p>
  
  <p>The event tracking works if I put it in my controller with this snippet:</p>
  
  <pre><code>$analytics.eventTrack('event', {category: 'category', label: 'label'});
  </code></pre>
  
  <p>Does anyone know what I might be doing wrong when adding the code to my links and buttons?</p>
  
  <p>EDIT</p>
  
  <p>I've tried to remove analytics-on="click" and instead just have analytics-on but that doesn't work either.</p>
  
  <pre><code>&lt;button ng-click="openModal()" analytics-on analytics-event="button" analytics-categori="Main page" analytics-label="Modal bottom"&gt;Open modal!&lt;/button&gt;
  </code></pre>
