Since the handle has no electrical parts, I recommend you to glue it back in the following way if you still have the broken pieces:
Parts to use: metal clothes hanger, a epoxy glue (from Home Depot)
Method: Cut a short piece of wire from the clothes hanger. The length should be short enough to fit inside the handle and act as an reinforcement for the broken handle. The epoxy glue has 2 tubes, resin and hardener. Follow the instruction of the epoxy package, mix equal amount from each tube. The quantity should be enough to fill up part of the handle with the hanger wire embedded. Drying takes a couple of hours but leave it overnight before you use it.
Hope this help...Clem
