[Brightness] Control brightness with function keys

Hello,

I want to be able to adjust the brightness with F5 and F6 function keys. First issue, xev was'nt able to detect them, I solved this thanks to this post. But now a new problem appear,  thses two keys don't have any keysym ! For example, when I press on the key to raise the volume, I get :

KeyPress event, serial 33, synthetic NO, window 0x1a00001,
    root 0x1c7, subw 0x0, time 706521, (122,453), root:(767,501),
    state 0x10, keycode 123 (keysym 0x1008ff13, XF86AudioRaiseVolume), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 33, synthetic NO, window 0x1a00001,
    root 0x1c7, subw 0x0, time 706521, (122,453), root:(767,501),
    state 0x10, keycode 123 (keysym 0x1008ff13, XF86AudioRaiseVolume), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

Here I know that in my i3 configuration, I have to use XF86AudioRaiseVolume. But when I press on the key to raise the brightness, I get this :

MappingNotify event, serial 33, synthetic NO, window 0x0,
    request MappingKeyboard, first_keycode 8, count 248

FocusOut event, serial 33, synthetic NO, window 0x1000001,
    mode NotifyGrab, detail NotifyAncestor

FocusOut event, serial 33, synthetic NO, window 0x1000001,
    mode NotifyUngrab, detail NotifyPointer

FocusIn event, serial 33, synthetic NO, window 0x1000001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 33, synthetic NO, window 0x0,
    keys:  0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0 

And if I press for decreasing the brightness :

FocusOut event, serial 34, synthetic NO, window 0x1000001,
    mode NotifyGrab, detail NotifyAncestor

FocusOut event, serial 34, synthetic NO, window 0x1000001,
    mode NotifyUngrab, detail NotifyPointer

FocusIn event, serial 34, synthetic NO, window 0x1000001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 34, synthetic NO, window 0x0,
    keys:  1   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0 

How should I configure my bindsym? For the moment I have:

bindsym XF86MonBrightnessUp exec xbacklight -inc 20

Thanks!
