Reset Script only works ONE TIME - recalbox 4.1

Hey. I built my SNesPi. (RaspberryPi inside an original Nintendo Snes Case and i want to keep the use as intuitive and original as possible.

So, i 3Dprinted an internal support to a button that is pressed when i press the original EJECT button on SNES console... The plastic just press the button and it´s tied to the GPIO 1P START Button. I am using 2 SNES controllers over USB on the same PI. So the SNES controllers are 1P, 2P and the GPIO is configured as 3P. 

Unfortunatelly  (And i can´t imagine WHY this designed light that), retroarch only accepts Overall emulator Key Bindings on Player 1 Controller. :( That´s not good for my case, because it just ignore any input from Player 3 (Snes case buttons on GPIO as Player 3). 


   That said, i just checked that my EJECT button is working nicelly on REcalBox 4.1 and i noticed that now, there´s an handy EXIT Python script included to exit games just pressing START on GPIO ! That´s perfect for custom cases ! 

    But i need an RESET button working too. So i got the code for RESET (Custom.sh + Python script) set everything and bam. It´s "working" but it only works one single time. I enter a game, for the first time after the boot. Press RESET on my snes (Wich is using GPIO (24) Button A) The rom is reseted on Retroarch (Network commands on), but if i just try it again, all the next  resets are ignored. :( 
  I really don´t know what´s wrong... 

  I even monitored the Terminal on that Pi, acessing it over SSH, and everytime i Rock the RESET switch, the terminal shows "RESET" message. But retroarch ignores it... (After the first reset...) 
 This reset is the same as pressing HOTKEY + A on Retroarch on 1P controller... And it´s working everytime pressing on 1P gamepad... But i would love to see it working with the original RESET switch on SNES too... I just changed the original python script from GPIO 3 to GPIO 24 because its the one i have wired on the switch (but i can change it to any pin)

  This is  the custom.sh : 

'''

#!/bin/sh
#custom.sh

case "$1" in
start)
python /recalbox/share/system/reset_btn.py
;;
stop)
;;
esac
exit $?

And the Python script :

import RPi.GPIO as GPIO
import time
import socket

addressing information of target

IPADDR = "127.0.0.1"
PORTNUM = 55355

enter the data content of the UDP packet

COMMAND = "RESET"

initialize a socket, think of it as a cable

SOCK_DGRAM specifies that this is UDP

try: s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
except socket.error: print 'Failed to create socket' sys.exit()

GPIO.setmode(GPIO.BCM)
GPIO.setup(24, GPIO.IN, pull_up_down=GPIO.PUD_UP)

def exitEmulator(channel):
s.sendto(COMMAND, (IPADDR, PORTNUM))

GPIO.add_event_detect(24, GPIO.FALLING, callback=exitEmulator, bouncetime=500)

while True: time.sleep(10)

Any help ?

Sorry. I don´t know how to remove text formatting on this forum.
