Rest service not triggered after updating a submission

Hello everyone, I have a rest service called when I submit a form for the first time. However, when I select one of the submission and make some changes, the Rest service is not called at all. I would expect my service to be called with the updated submission.
Is there anything I can change to make this work?

aside: the XLSForm function uuid does not work with a param in a calculated field is this correct?
