Review and fix the purpose of `updateXFormWithTemplate`

> If I recall correctly those set of methods are meant to update the form generated by the binding, trying to fulfill what the user set in the `PartialTD` passed in the `produce` method. My guess is that using them in two different bindings causes some possible collisions 🤔 . However, the methods are poorly implemented and I think we should review them in the future. I propose merging this PR and keeping track of this issue.
