Why is my save function for my Data Store Script not saving?

Hi, I have a data store script that gets data and saves data. But the saving part doesn't work. I've tested it by changed a player's cash value and added print functions on getting the data and saving the data. The print function on getting the data works but nothing for saving the data. No errors or etc was warned to the output. This is the script:

local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("ServerDataStore")
local discordModule = require(game.ServerStorage.DiscordModule)

game.Players.PlayerAdded:Connect(function(player)
	local successValue = false
	for i = 1,3 do
		local success,data = pcall(function()
			return myDataStore:GetAsync(player.UserId)
		end)
		local leaderstats = Instance.new("Folder",player)
		leaderstats.Name = "leaderstats"

		local cash = Instance.new("IntValue",leaderstats)
		cash.Name = "Cash"

		local xp = Instance.new("IntValue",leaderstats)
		xp.Name = "Exp"

		if success then
			successValue = true
			if data then
				local table2 = data
				cash.Value = table2[1]
				xp.Value = table2[2]
				break
			else
				cash.Value = 0
				xp.Value = 0
				break
			end
		else
			warn("Data could not be retrieved! Retrying...")
		end
	end
	if not successValue then
		discordModule.sendMessage("Player_"..player.UserId.."'s data could not be retrieved!")
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local successValue = false
	for i = 1,3 do
		local myTable = {}
		table.insert(myTable,1,player.leaderstats.Cash.Value)
		table.insert(myTable,2,player.leaderstats.Exp.Value)
		local success,errormessage = pcall(function()
			myDataStore:SetAsync(player.UserId,myTable)
		end)
		if not success then
			warn("Data could not be saved! Retrying... Error:",errormessage)
			return
		elseif success then
			successValue = true
			break
		end
	end
	if not successValue then
		discordModule.sendMessage("Player_"..player.UserId.."'s data could not be saved!")
	end
end)

Please Help!
