Datastoring tables not saving the value?

I am Datastoring tables, having a bit of an error using :SetAsync() function. When I use the SetAsync function, it doesn't really set the PlayerData is the Module script for that player. I need help, the output doesnt output any errors.

Module Script:

return {
    PlayerData = { Coins = 0, Diamonds = 0, Experience = 0, Kills = 0, Level = 0, EXPneeded = 0, }
}

Script:

local DataStore = game:GetService("DataStoreService"):GetOrderedDataStore("PlayerDataV1");
local DataModule = require(game.ReplicatedStorage.PlayerData)


game.Players.PlayerAdded:Connect(function(plr)
    for i, v in pairs(DataModule.PlayerData) do
        DataStore:GetAsync(plr.UserId, v)
    end
end)

game.Players.PlayerRemoving:Connect(function(plr)
    for i, v in pairs(DataModule.PlayerData) do
        DataStore:SetAsync(plr.UserId, v) -- v; the value of the instances when looped through the table.
    end
end)
