Registration Form Field isn't saving in db

Hi there,

I'm trying to add a field in the registration form, I already did actualy.
The field is in the Admin panel, in the registration and etc. But ins't saving in the DataBase column.

Can you help me? the column is already created in the db. I changed the files based on this link: http://nopcommerce.codeplex.com/SourceControl/changeset/changes/a179ce882d6b
