[jQuery] Dynamic checkbox not included in submit by jquery.form

[jQuery] Dynamic checkbox not included in submit by jquery.form

Hello,
I have a form with a drop down list which populates a div with checkboxes based on an AJAX query each time it changes.
I'm then using ajaxSubmit to post that data along with a few additional form elements.  All of the elements are included in the post <u>except for the checkboxes</u>.
HTML and code snippets are listed below... the checkboxes are populated in div#account.
Any suggestions?
thanks,
Michael
