title: JS Analytics Ecommerce callback
body: <p>I couldn't find anywhere how to use <code>hitCallback</code> parameter with google analytics <code>ecommerce:send</code>. In docs its only example is with <code>send,pageview</code>.</p>
  
  <p>Here is the code I tried:</p>
  
  <pre><code>ga('ecommerce:send',
     {'hitCallback': function() {window.location.href="/test.php";}}
  );
  </code></pre>
  
  <p>but it didn't work although the tracking worked.</p>
