Why wont the cooldown work?

function createExplosionForPlayer(client, command) 
    local cooldown = 300 
    local commandname = "jihad" 
    local note_info = "You need to wait 5 minutes before you can do this again." 
    local note_active = "Cooldown is still active, please wait." 
    local timer = getElementData(client, "jihad.cooldown") 
    if not timer then 
        if (isPedInVehicle(client)) then 
            outputChatBox("You can't commit a Jihad in a vehicle!", client) 
        return 
        end 
        setTimer(createJihadForPlayer, 2500, 1, client, x, y, z) 
        triggerClientEvent("playTheSound", root, client) 
        setPedAnimation(client, "BOMBER", "BOM_Plant") 
    end 
end 
addCommandHandler("jihad", createExplosionForPlayer) 
  
function createJihadForPlayer(client, x, y, z) 
    if (isPedInVehicle(client)) then 
        outputChatBox("You can't commit a Jihad in a vehicle!", client) 
    return 
    end 
    local x, y, z = getElementPosition(client) 
    createExplosion(x, y, z, 2) 
    createExplosion(x, y, z, 3) 
    createExplosion(x, y, z, 10) 
    outputChatBox(getPlayerName(client) .. " committed a Jihad!", root) 
end 
addCommandHandler("c2", createJihadForPlayer)
