Refresh of udev rules directory does not work

I try to edit, remove and create rules in udev. For some reason, those rules are not activated, even when I try the known solutions-

1. Udevadm control –reload-rules
2. Udevadm trigger
3. Just reset the the udev service.

It only works when I reboot the machine (which means that the rules are written correctly). What should I do in order to enforce an immediate enforcement of rules?
