Ubuntu – How to rebind “Initiate Window Move” to mouse button 10

I am trying to use button 10 on my mouse to drag windows around. I have installed CCSM and changed the initiate button in the plugin "Move Window" to "Button10" (with no modifier, though adding modifier keys to test does not help).

I know that the desired button is number 10 because xev reports

ButtonPress event, serial 36, synthetic NO, window 0x4000001,
    root 0x15d, subw 0x0, time 8361012, (77,129), root:(1812,182),
    state 0x0, button 10, same_screen YES

ButtonRelease event, serial 36, synthetic NO, window 0x4000001,
root 0x15d, subw 0x0, time 8361286, (77,129), root:(1812,182),
    state 0x0, button 10, same_screen YES

when I click that button in its window.

There is no effect when pressing button 10 with these settings. However, I know that I'm changing the correct setting, as switching from the default of Alt+Button1 to e.g. Ctrl+Alt+Button1 does take effect.

Edit: output of xinput list --long 10 as requested by Braiam.
