Default exFAT - how to add so system auto mounts device?

My device didn't support exfat, so I compiled a kernel module and also the fuse modules, and I can successfully mount the device using terminal emulator, however I want the device to auto mount on the insertion of a exfat flash drive or sdcard like it would a fat32 drive, but for some reason it still won't auto mount when I plug in exfat device it just shows notification "damaged storage"

so does anyone have any idea how I can add this filesystem to the android list of supported partitions detection mechanism ?

I know there are programs on the playstore like stickmount ..etc but I want to integrate it into the main functionality of android if possible

I am rooted and have full access to the device, I am running android 4.2.2

any ideas would be great
