CI validation radio buttons with Ajax

It works perfectly apart from my radio buttons! When I submit the form, they're not repopulating I have checked in my controller and they're getting the value...I just don't know what has gone wrong...

view:

Code:

form_label('Joint application?:');
form_radio('joint_application', '1', set_radio('joint_application', '1', FALSE), 'class="joint_application"').' Yes';
form_radio('joint_application', '2', set_radio('joint_application', '2', TRUE), 'class="joint_application"').' No';

...actually they're not getting the value

Not sure if it's the problem but according to the userguide
you don't set "FALSE" to the seocond element. Only "TRUE" for
the default one.
