Kotlin RecyclerView - Update item to DB - android-studio

Question

I have a category item in my recyclerView.
There is a TextView and two ImageView as button (Edit button and Delete button).
When I click edit button I want to change TextView to EditText and editbutton change for agreebutton. When I write new text just update my old one.
I show you what I have and almost everything working but don't update my new text and I know code don't look nice and maybe someone can show me how to do it better :)
class CategoryAdapter(private val categoryList: List<Category>, val listener: ClickListener) : RecyclerView.Adapter<CategoryAdapter.MyViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
return MyViewHolder(CategoryItemBinding.inflate(LayoutInflater.from(parent.context), parent, false))
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
holder.binding.categoryName.text = categoryList[position].name
holder.binding.categoryEditIv.setOnClickListener {
holder.binding.categoryName.visibility = View.GONE
holder.binding.categoryEditName.visibility = View.VISIBLE
holder.binding.categoryEditName.setText(categoryList[position].name)
holder.binding.categoryEditIv.visibility = View.GONE
holder.binding.categoryAgreeIv.visibility = View.VISIBLE
}
val editTxt = holder.binding.categoryEditName
holder.binding.categoryAgreeIv.setOnClickListener {
val edit = editTxt.text.toString()
listener.editAgreeClickItem(edit)
holder.binding.categoryName.visibility = View.VISIBLE
holder.binding.categoryEditName.visibility = View.GONE
holder.binding.categoryAgreeIv.visibility = View.GONE
holder.binding.categoryEditIv.visibility = View.VISIBLE
}
holder.binding.categoryDeleteIv.setOnClickListener {
listener.deleteClickItem(categoryList[position])
}
}

return categoryList.size
}
