Trying to delete a model spawned from a script out of workspace, can someone give me a hand?

I tried different ways to delete a model from workspace but it wont work, here is the script that will not do anything. Anything will help like any roblox scripting support links I have not looked at.

function spawnmodel()
	for k,v in pairs(workspace:GetChildren()) do
		if string.find(v.Name:lower(), "TestModel") then
			v:Destroy()
		end
	end
end
script.Parent.MouseButton1Down:connect(spawnmodel)
