title: Passing in parameters to controllers from Ember handlebar actions
body: <p>I want to send extra information from my handlebars script to my controller; this is my code:</p>
  
  <pre><code>&lt;a {{action "resetState" data="state1" }}&gt;reset1 &lt;/a&gt;
  </code></pre>
  
  <p>I can't retrieve state1 in my controller; how do I send extra strings to the backend?</p>
