Can not associate file types on safari with iphone application

Question

I'm making an sample application which can read and share many kind of files,included docs, videos, audios, images,... One of most important its feature is associate with mail attaches and Safari. In fact, I did open successfully docs in mail attaches following the tutorial in here but it was not working on Safari. I tried an another application which can open document file and it works perfectly on Safari.

This is a part of my plist file:
