First update the data of that specific position item of adapter.

After that call notifyItemChanged(int) to update that specific CardView of RecyclerView

Notify any registered observers that the item at position has changed. Equivalent to calling notifyItemChanged(position, null);

This is an item change event, not a structural change event. It indicates that any reflection of the data at position is out of date and should be updated. The item at position retains the same identity.
