Auto updating model, not working? Any fixes?

I'm using the code from the Roblox wiki specifically made for this question, but it is not doing what it's supposed to be doing, I want a model that auto updates to the current version of itself when a new version is published but the model just sits there and stays as the outdated version. Very confusing

local model = script.Parent
local modelID = 693015809 -- Change this to the model id of the model you created earlier

function checkUpdate()
    local newModel = game:GetService("InsertService"):LoadAsset(modelID)

    if model.Version.Value < newModel.Version.Value then
         newModel.Parent = model.Parent
         model:remove()
    end
end

checkUpdate() -- You can either put this in a loop, or call it once. I reccomend calling it once.
