Try ViewCompositionStrategy DisposeOnLifecycleDestroyed

I remember something about the docs not being exactly right about this one

What I did is ```binding lifecycleOwner let val strategy = ViewCompositionStrategy DisposeOnLifecycleDestroyed it setViewCompositionStrategy strategy ``` and in the init block of my ViewHolder I have to set binding s lifecycleOwner manually with ``` init binding lifecycleOwner = parent findViewTreeLifecycleOwner ``` but I am not sure if this solution is an equivalent of whet they suggest in the documentation

according to the documentation these two strategies work differently
