FragmentStateAdapter for ViewPager2 notifyItemChanged not working as expected

Question

I am using ViewPager2 with FragmentStateAdapter and i am calling notifyItemChanged(position). But as expected createFragment method not calling again. Is it is the intended behavior or bug, what should I do

My Code is

    class EEditionPagerAdapter(
    fragmentManager: FragmentManager, lifecycle: Lifecycle, private var date: String
    ) : FragmentStateAdapter(fragmentManager, lifecycle) {

    private var menuList = emptyList<EEditionMenu>()

    override fun getItemCount(): Int = menuList.size

    override fun createFragment(position: Int): Fragment {
        val menu = menuList[position]
        return EEditionListingFragment.newInstance(menu, date)
    }

    fun submitList(list: List<EEditionMenu>) {
        menuList = list
        notifyItemRangeChanged(0, menuList.size)
    }

    fun changeDate(date: String, position: Int){
        this.date = date
        notifyItemChanged(position)
    }
}

FragmentStateAdapter uses item IDs to determine if a fragment has already been created and reuses already created ones. By default, an item ID is the item's position. You can override getItemId and containsItem to provide your own unique IDs based on positions and dates, then it will ask for a new fragment when the date changes.
