title: add class to element in template event
body: <p>This Meteor template code tries to add class to the element without unnecessary calls. <code>event.currentTarget.addClass('active');</code> failed to add the class? What am I doing wrong?</p>
  
  
  
  <pre class="lang-js prettyprint-override"><code>// inside the template events
  'click #login-form-link': function (event) {
      $('#login-form-link').addClass('active'); // extra call
      event.currentTarget.addClass('active');   // cheap but did not work
   },
  </code></pre>
