Hi Hafidhh
I have tested your library on an Arduino Leonardo Board, more exactly and Arduino Things Uno Board based on Arduino Leonardo architecture, and interrupt has not been working.
Researching for possible causes, i found that Interrupt Pin versus Interrupt Number, is not fixed on all boards, and arduino recommend to use the translation funcion attachInterrupt(digitalPinToInterrupt(this->_pin) as mentionated here https://www.arduino.cc/reference/en/language/functions/external-interrupts/attachinterrupt/
I tested now and is working!
I hope this can help other users.
Best Regards
