Turbosmooth custom modifier

Hello,

I would like to ask your helps, because i can't find any solution and documentation about my problem:(
I want to make a script for myself, with i can add instanced custom turbosmooth modifier for objects. These will use paramteres from a custom attribute on rootnode.
With this i can manipulate all of the turbosmooths on my highpolys from my dialog.
I know it can be easier if i just put an object in the scene with turbosmooth, and instance from it, but i don't want to add any node to the viewport for this. And other hand, i just want to learn some tricks:)

So my problem is, if i just add a simple spinner to control the iteration separatedly, the modifier stop updating itself compare to the original TS. I don't really know why the custom rollout kill the auto mesh update. Maybe i can add an 'update $' or something after the delegate, but it won't work, if it need to run on instanced objects.

Hope somebody can help me how to fix this. Thank you!
