There's no XF86MonBrightnessUp/Down key in laptop?!

Hi!
I'm trying to configure brightness settings in i3. I found brightnessctl and I was going to use it for controlling my screen brightness in i3 but when I tried to bind it to XF86MonBrightnessUp/Down it didn't work. I used xev and pressed fn+f7 (it's the key that has the brightness down icon on it in my laptop(G731)) and it didn't output anything for it!! Then I used evtest and realized that there's no key for controlling the brightness! I even used acpi_listen but there was no luck with that either.
So, what can I do for controlling my brightness with keys? Is there another way to control the brightness?

Search https://wiki.archlinux.org/index.php/Laptop/ASUS for backlight - tips for some other models might be applicable (eg. acpi_osi)
