jQuery-File-Upload not firing done callback in Internet Explorer (IE9)

Question

i checked some questions regarding the same issue, blueimp jquery file upload - "done", "complete" callbacks not working for IE 9 , but even after puttin

Answer 1

ok so i go it working.The problem was that in the fileuploader configuration i had

dataType: 'json'

but since IE9 uses the iframe it makes a html request, and the response has the Content-Type 'text/html'. With that configuration the fileuploader is expecting to receive a json response so my response was going to a fail callback i made just for testing. Got it working by looking at this post jQuery FileUpload doesn't trigger 'done'
