Footer Row failing to Insert into table via asp gridview - asp.net

Question

I'm working with vb.net and have followed a tutorial to set up a gridview to update/delete/insert records into a table. I have a footer row that isn't working for me. when I click my insert button the textboxes from the footer do not do the insert. I think I am missing something fundamental that is causing this. May the page is posting back before the sub grabs the text from the textboxes? My understanding of it is pretty but I feel this could be the issue because I have two radio buttons that I use to switch between SQL data adapters because I want to be able to work with different tables. I have these set to postback="true". Could that be my issue?

End Sub

e.command.parameters("productionsdt").Value = Newproductionsdt.Text

End Sub
I know its a lot to look at but again I feel my issue might not be with the code so much as me missing a concept. Thanks in advance for any ideas/suggestions.
