Samsung np500p4c Keyboard backlight not working.

Hello,
I have been on arch from few days and other things are working fine but the keyboard backlights. I have followed arch guide for keyboard backlight https://wiki.archlinux.org/index.php/Keyboard_backlight but nothing works. Please tell me which way i should be headed to solve this issue.

This is the output of /usr/local/bin/kb-light.py +

Traceback (most recent call last):
  File "/usr/local/bin/kb-light.py", line 25, in <module>
    print(kb_light_set(1)) # ./kb-light.py (+|--up) to increment
  File "/usr/local/bin/kb-light.py", line 11, in kb_light_set
    current = kbd_backlight.GetBrightness()
  File "/usr/lib/python3.5/site-packages/dbus/proxies.py", line 70, in __call__
    return self._proxy_method(*args, **keywords)
