it stop working because of the batteries. they go fast, so i bought rechargeable batteries and once they were fully charge ( i switched to the keyboard to be sure) i placed them on the Magic Tracktad, it does click but doesn’t move the pointer- it is a software issue or just simple a hardware malfunction?

Go to the System Preferences under the Apple to Bluetooth and see if the trackpad is discoverable. If so you may need to match it to your computer.
