Panic button is not sending any signal to zstick controller

I am developing an IOT platform in java using zwave4j.jar driver.
I have an Aeon lab zstick and a panic button. I can successfully pair them by putting zstick in inclusion mode and pushing the “learn” button on panic button. I can see the panic button is listed in nodes list in zstick controller but when I push the main button on panic button there is no trigger message coming to zstick.
please help me in this regard, I want to receive a notification on zstick controller event listener when I trigger the panic button just like when a smoke sensor is triggered.
