The problem I am having is to have the changes reflected back to the database table. i.e. updation.

It's pretty clear to me where this is coming from. In the first instance especially, updation is one of the four basic database operations: select, insert, delete, update. The other three have nice nominal forms: selection, insertion, deletion. Update is, uh, ... update. The temptation to make a form parallel with the rest is very strong.
In fact, it's a strong enough temptation that Google gets 195,000 hits, with much un-self-conscious use for the term:
In searching for cites, I also found a forum post entitled "Updation is not a word." Yeah, well ... not yet.
