[jQuery] reference dynamically loaded form select

Been trying to find the best answer to a problem a co-worker is having
with a form select field that gets loaded via an ajax call into a
table cell.

He has a form and when the page loads based on the value of another
form field he makes an ajax call and loads a complete select
statement.

the ajax load is fine, but when he makes a select from the new select
this it is not recognized and passed with the form submit.

How can I get this select field to be recognized by the form?

Thanks for any insight.
