GUI button that places a model?

I am making a plugin called "City Maker" and I made the plugin in the ServerStorage as well as the Apartment model that I made, I have made a GUI buttun that is supposed to place down a model (the Apartment) but it does not. If somebody tells me the code I have to insert into the button it would solve all my problems.

Here is the code I have so far:

Instance.new("ClickDetector", script.Parent)
function onClick(player)
local model = game.ServerStorage.Apartment

local backup = model:clone()

while true do
    wait(5)






    model = backup:clone()
    model.Parent = game.Workspace
    model:makeJoints()

end

end
