How do i attach/parent Cloth Physics object on another Cloth Physics object?

I have a problem in attaching this two physics object. When i use apex control painting to lock the seam, Cloth 2 move pretty nice meanwhile cloth 1 does not simulate properly [stay still like a rock]. If i don’t lock the seam, Cloth 1 would simulate properly but cloth 2 would fall off or fly somewhere else because their vertex does not connect. Do you have any idea how to solve this?
