[HELP] Why not working onPlayerQuit event?

[Tokio]

this is my code:

function onQuit(thePlayer)
for i,v in pairs(getElementsByType("vehicle",resourceRoot)) do 
if getElementData(v,"oveie") == getPlayerName(thePlayer) then 
destroyElement(v) 
end 
end 
end
addEventHandler ( "onPlayerQuit", root, onQuit )

but this does not working..  why? how to fix it?

-- setElementData ( vehicle, "onQuit", player ) -- do not forget it ( add it to the vehicle which belongs to the player )

function onQuit ()
	for _, v in ipairs ( getElementsByType ( "vehicle" ) ) do 
		if getElementData ( v, "onQuit" ) == source then 
			destroyElement ( v ) 
		end 
	end
end
addEventHandler ( "onPlayerQuit", root, onQuit )
