Show comments inside fancybox

Hi

can you please guide me how to show comments inside a fancybox.
http://fancyapps.com/fancybox/

i tried , but this would reload whole page.
i must tell you here that the parent page where fancybox ajax link is placed already has a comment form which works exceptionally well.
