Lua Own Backpack Not Working?

[Alyhide]

Hello, I am using a mod made by Cykotitan, it's your 'Own Backpack' the thing is, it says "It is owned by blah blah." but any other player can open it o.0

<mod name="Own Loot Backpack" enabled="yes">
	<config name="ownbp_config"><![CDATA[
		config = {
			itemid = 10521,
			cost = 1000000
		}
	]]></config>
	<talkaction words="!backpack" event="buffer"><![CDATA[
		domodlib('ownbp_config')
		if doPlayerRemoveMoney(cid, config.cost) then
			local backpack = doPlayerAddItem(cid, config.itemid, 1)
			doCreatureSay(cid,"You Have Bought A Private Backpack!",19)  
			doItemSetAttribute(backpack, "description", getPlayerName(cid) .. ' owns this container.')
			return doItemSetAttribute(backpack, "aid", getPlayerGUID(cid) + 1000)
		end
		return doPlayerSendCancel(cid, "You don't have enough money, it costs " .. config.cost .. " gold.")
	]]></talkaction>
	<action itemid="2000" event="buffer"><![CDATA[
		_result = item.actionid >= 1000 and item.actionid - 1000 ~= getPlayerGUID(cid) and doPlayerSendCancel(cid, 'You\'re not owner of this container.')
	]]></action>
</mod>

Does it say "Youre not owner of this container" when you open the backpack?

No, it says nothing, anyone can open the backpack without error.
