então como faço para esse comando funcionar?
bindKey("k","down",function ()
if not isEventHandlerAdded("onClientRender", root, inventario ) then
showCursor (true)
addEventHandler ("onClientRender", root, inventario)
changeVisibility("qtd", true)
end
end)
bindKey("BACKSPACE", "down", function()
if isEventHandlerAdded("onClientRender", root, inventario )then
removeEventHandler("onClientRender", getRootElement(), inventario)
showCursor (false)
changeVisibility("qtd", false)
end
end)
