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!
