To Reproduce
Steps to reproduce the behavior:

1. Go to http://localhost:5080/auth/clients/email%2Fbastien%40nextcairn.com%2Ftc-notify-test
2. Login with fake credentials (e.g., clientId test and accessToken test)
3. Click on the "Delete on Expiration" switch

Actual behavior
The save button is not clickable after making a change to the "Delete on Expiration".

Expected behavior
The save button should be clickable

Additional context
The button becomes clickable when a user changes any of the other fields. It just doesn't work for the switch for some reason. Let's fix that.

Can I work on this issue?

@Rolikasi you mentioned it's hard working on multiple issues at once.. one way to avoid that is working on only one or two at a time :)

I would like to work on this!
