Why models can't detect touch with this script?

Put this inside of a model but nothing happens. Please help, thank you! <3

local debounce = false

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		if debounce == false then
			debounce = true
			player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + 1
			wait(1)
			debounce = false
		end
	end
end)

Models don't detect touches. If this is some sort of NPC the player is supposed to be touching, put the script in their Head or HRP, some sort of part in the NPC you would be able to hit.
