Changing "AttachmentPos" in Character scaling Script dosent do anything?

So i have an character Scaling Script that used Hats so i updated it to use Accessory but changing the AttachmentPos in properties and in script didnt seem to do anything? Any help?

function scaleCharacter(model,scale)
        if not model or not scale then return end
        if not _G.ScaleCons then
                _G.ScaleCons = {}
        end
        if _G.ScaleCons[model] then
                _G.ScaleCons[model]:disconnect()
        end
        local joints = {}
        local parts = {}
        local h = model:findFirstChild("Humanoid")
        if h then
                h.Parent = nil
        end
        local function handleHat(hat)
                if hat:findFirstChild("GotScaled") then return end
                Instance.new("Flag",hat).Name = "GotScaled"
                spawn(function ()
                        local h = hat:WaitForChild("Handle")
                        local m = h:WaitForChild("Mesh")
                        m.Scale = m.Scale * scale
                end)
                local yInc = (scale-1)*.5
                hat.AttachmentPos = (hat.AttachmentPos * scale) - (hat.AttachmentUp * Vector3.new(yInc,yInc,yInc))
        end
