Eajaxupload problem with Fancybox

Hi all,

I would like to use eajaxupload to do upload file, i have to try to apply it in normal page and it work very well, but once i using fancybox prompt out, it didnt show the upload button. I think it is because the widget doesn’t start. can anyone tell me what wrong with it? or should i need to change/add any coding?
