I have a custom visualforce page that looks like this:


Basically, it's a list of identifiers for an account (this is embedded on the account page). Everything behaves as I expect, I can add and remove rows, and when I click "edit" the input fields become active so the data can be modified and the "Edit" changes to "Ok". When I click "Ok" I want the data to be changed and the view to be refreshed with the updated data. However, when I do this, say, changing "12345" to "11111" I click OK and the data reverts back to what it was. I'm not exaclty sure what is going on. Any help would be appreciated. Code is below for reference.
