not working in recyclerview adapter

[karthi72]

I just integrated the code to my recycler view adapter and there I cant able to handle single item click submit after selection.

class ProductsAdapter : RecyclerView.Adapter() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MovieViewHolder {

    val inflater = LayoutInflater.from(parent.context)

    return MovieViewHolder(inflater, parent)

}
override fun onBindViewHolder(holder: MovieViewHolder, position: Int) {
    holder.bind()
}

override fun getItemCount(): Int = 10}

class MovieViewHolder(inflater: LayoutInflater, parent: ViewGroup) :
RecyclerView.ViewHolder(inflater.inflate(R.layout.item_product, parent, false)),
OnStateListener {
private var mTitleView: TextView? = null
private var mIncrementProductView: IncrementProductView? = null

init {
    mTitleView = itemView.findViewById(R.id.amount)
}

override fun onCountChange(count: Int) {

    mTitleView?.text = "$" + count * 45;
}

override fun onConfirm(count: Int) {
    Toast.makeText(itemView.context, "Confirm Count : $count", Toast.LENGTH_SHORT).show()
}

override fun onClose() {
    Toast.makeText(itemView.context, "Close Action", Toast.LENGTH_SHORT).show()
}

fun bind() {
    mTitleView?.text = "23"
    mIncrementProductView?.setOnStateListener(this)

    mIncrementProductView?.setOnClickListener {
        Toast.makeText(
            itemView.context,
            "Position clicked $adapterPosition",
            Toast.LENGTH_SHORT
        ).show()
    }
}

}
