title: Refreshing Magento checkout step
body: <p>I have added functionality to Payment method step, which is related to shipping address, if shipping address changes, then Payment method HTML content must be reloaded. I tried to add JavaScript to Billing and Shipping step, but my backend requires that Shipping address is saved to work. So If I add my own JavaScript after onclick="shipping.save();" in shipping.phtml, it is never called. </p>
  
  <p>Is there way to refresh step HTML every time step is viewed?</p>
