Update Lease End Date vRO

I'm trying to update the lease expiration date of a deployment in vro.  I read this thread, and it gave me a good base to start with, but i can't seem to get the operations peice to work.

My end goal is to publish a link via email to the end user for POC boxes so they can extend the lease without any intervention.  I've attached the code i'm working with just to flesh out how everything works.

I have the code to grab all vm's expiring in less than 30 days and the code to grab the deployment catalog resource.  Just can't get the operations to populate.

Any help is greatly appreciated.
