Each time replacing brake pads do I need to install new Electronic Wear Sensor as well?
You only need to change them if they are worn out. If the wires part of the sensor are exposed are showing, you will need to replace them. If you got the message on your instrument cluster saying that you need to replace the brake pads, then you most likely will need to replace the sensor.
