Dynamic Radio Button list in HTML table

Question

I have a pre-existing table on a web page and need to insert a dynamic radio button list into one cell of the table.  This is for upselling hotel rooms and the list contents and order are data-driven.  Selection of a radio button option must cause an autopostback.  I've tried a number of approaches but each fails at the point where I try to get the value data after the postback fires.

What I did was duplicate the HTML that .NET generates from the ASP control.  I'm obviously missing something on getting the value passed back in the postback event.

Any help appreciated.
