title: Running observer after "Billing Information" in Magento onepage checkout
body: <p>I am trying to run an observer directly after the user has clicked 'submit' on the 'Billing Information' on the onepage checkout in Magento.</p>
  
  <p>Here is the code I have in my module xml but having no joy at the moment</p>
  
  <pre><code>       &lt;events&gt;
          &lt;controller_action_predispatch_checkout_onepage_savebilling&gt;
              &lt;observers&gt;
                  &lt;ss_raptor_model_observer&gt;
                      &lt;type&gt;singleton&lt;/type&gt;
                      &lt;class&gt;SS_Raptor_Model_Raptor_Observer&lt;/class&gt;
                      &lt;method&gt;afterBillingMethod&lt;/method&gt;
                  &lt;/ss_raptor_model_observer&gt;
              &lt;/observers&gt;
          &lt;/controller_action_predispatch_checkout_onepage_savebilling&gt;
       &lt;/events&gt;
  </code></pre>
  
  <p>I am using magento 1.7 - can anyone confirm what I am doing wrong?</p>
