title: Send enhanced ecommerce data
body: <p>When i land on the confirmation page i run the following code.</p>
  
  <pre><code>var purchaseObject = {
    'id': $OrderID,
    'revenue': $total,
    'shipping': $deliverycost
  };
  if (couponCode.length) {
    purchaseObject['coupon'] = couponCode;
  }
  ga('ec:setAction', 'purchase', purchaseObject);
  ga('ec:send');
  </code></pre>
  
  <p>Both sends generates error messages.</p>
  
  <blockquote>
    <p>Plugin "ec" does not have method "send".</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>Error calling a plugin method: {0: "ec:send"}</p>
  </blockquote>
  
  <p>I have added</p>
  
  <pre><code>ga('require', 'ec');
  </code></pre>
  
  <p>in the head and the other events works so i don't get why the send does not work. </p>
