android kotlin recyclerview databinding Kotlin

Could someone explain I need help solving I'm experiencing an issue where clicks on items in my RecyclerView are not being registered correctly after the data is updated... I'm using Android 14 with Kotlin and data binding to manage my UI state. The click listeners seem to work initially, but after I call `notifyDataSetChanged()` on my RecyclerView, the click events stop firing. I've ensured that the click listener is set correctly in the `onCreateViewHolder` method. Here’s a simplified version of my adapter code: ```kotlin class MyAdapter(private var items: List<MyItem>) : RecyclerView.Adapter<MyAdapter.MyViewHolder>() { inner class MyViewHolder(val binding: ItemLayoutBinding) : RecyclerView.ViewHolder(binding.root) { init { binding.root.setOnClickListener { // Handle click event val position = adapterPosition if (position != RecyclerView.NO_POSITION) { // Do something with items[position] } } } } override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder { val binding = ItemLayoutBinding.inflate(LayoutInflater.from(parent.context), parent, false) return MyViewHolder(binding) } override fun onBindViewHolder(holder: MyViewHolder, position: Int) { holder.binding.itemText.text = items[position].text } override fun getItemCount(): Int = items.size } ``` When I update my list in the Activity or Fragment and call `adapter.notifyDataSetChanged()`, the click events no longer work, but if I call `adapter.notifyItemChanged(position)`, the clicks seem to register. I’ve tried using `notifyItemRangeChanged()` as well, but it didn't help. Additionally, I verified that the bindings are correct and nothing in my layout is intercepting the touch events. Any insights on why this behavior persists and how to resolve it? Is there a best practice for handling such updates in a RecyclerView with data binding? Any ideas what could be causing this? Has anyone else encountered this?
