This looks like a good fix but we can't merge it into ytp-request (as job_title and affiliation are properties introduced in ckanext-unaids). This change should go alongside extending the UI tables for membership request inside ckanext-unaids.
I don't see any easy way to do this though. The change requires editing internals of ytp-request controllers and changing methods signatures. I suggest we drop this change and keep the job title and affiliation out of the emails being sent for the reuqest.
