Datastore not saving player data when they leave?

local dataStoreService = game:GetService("DataStoreService")
local dataStore1 = dataStoreService:GetDataStore("PlayerCurrency")
strength = dataStoreService:GetDataStore("Strength")
meditation = dataStoreService:GetDataStore("Meditation")
function create(name,classname,parent)
    local it = Instance.new(classname)
    it.Parent = parent
    it.Name = name
    return it
end
game.Players.PlayerAdded:Connect(function(plr)
    local ls = create("leaderstats","Folder",plr)
    local med = create("Meditation","IntValue",ls)
    local str = create("Strength","IntValue",ls)
    str.Value = strength:GetAsync(plr.UserId) or 0
    med.Value = meditation:GetAsync(plr.UserId) or 0

game.Players.PlayerRemoving:connect(function(plr)
    dataStore1:SetAsync(plr, meditation.Value)
    dataStore1:SetAsync(plr, strength.Value)
end)
end)

Im trying to make it save the values on the leader stats when the player leaves may someone help please thanks!
