DataStore script doesn't save/load attributes?

This works for my leaderboard but not for my attributes(Dex, Hp etc..) values. My output log says it's saved after leaving and loaded when I enter the game.

-- Saving
game.Players.PlayerRemoving:connect(function(player)
    local datastore = game:GetService("DataStoreService"):GetDataStore(player.userId.."att")

local statstorage = player:FindFirstChild("attributes"):GetChildren()
for i =  1, #statstorage do
    datastore:SetAsync(statstorage[i].Name, statstorage[i].Value)
    print("saved data number "..i)

end
print("Att successfully saved") 
end)

-- Loading
game.Players.PlayerAdded:connect(function(player)
        local datastore = game:GetService("DataStoreService"):GetDataStore(player.userId.."att")

    player:WaitForChild("attributes")
    wait(1)
    local stats = player:FindFirstChild("attributes"):GetChildren()
    for i = 1, #stats do            
    stats[i].Value = datastore:GetAsync(stats[i].Name)
    print("Att number "..i.." has been found")
        end
end)
