Datastore does not save when player leaves?

Hi there! My datastore save script won't work. But, when I execute it using the command line, it does. Any help is welcome.

local DataStoreService = game:GetService("DataStoreService")
local Wins = DataStoreService:GetDataStore("Wins")

game.Players.PlayerRemoving:connect(function(player)
	print('player left')
	local success, newName = pcall(function()
		return game:GetService("DataStoreService"):GetDataStore("Wins"):SetAsync(114962047, 55)
	end)
	 
	if success then
		print("success")
	end
end)

Thanks in advance, Jonas
