Adapter update clears the header view at 0th position as well when updating

[wishygupta]

I have horizontal recyclerview which is placed at 0th position of the adapter - lets call this as story group
I crated a bindableitem class which holds horizontal recyclerview

Next I have group of items which comes below the comes below it. - lets call this as post group
On click of any element of horizontal recycler view I am updating the adapter giving a new list of post group using groupAdapter.update(postsGroup)
After the update happens the story group recyclerview gets removed.
How can I not make it remove or do I have to place it in something else?
