RecyclerView OnClickListener not firing

Question

I aim to make a simple to-do list and for that I have used RecyclerView. My issue is that the OnClickListener() in the RecyclerView adapter class is not getting called. I have no idea why this is happening.

P.S I am fairly new to Android Development so please excuse any stupid mistake I have made.

RecyclerView adapter class:

import android.content.Intent
import android.util.Log
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.TextView
import android.widget.Toast
import androidx.core.content.ContextCompat.startActivity
import androidx.recyclerview.widget.RecyclerView
import com.google.android.material.card.MaterialCardView
import kotlinx.android.synthetic.main.activity_task.*
import kotlinx.android.synthetic.main.item_todo.view.*
import java.text.SimpleDateFormat
import java.util.*

class TodoAdapter(val list: List<TodoModel>) : RecyclerView.Adapter<TodoAdapter.TodoViewHolder>() {


    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): TodoViewHolder {
        return TodoViewHolder(
            LayoutInflater.from(parent.context)
                .inflate(R.layout.item_todo, parent, false)
        )
    }

    override fun getItemCount() = list.size

    override fun onBindViewHolder(holder: TodoViewHolder, position: Int) {
        holder.bind(list[position],position)
        holder.itemView.setOnClickListener {
            Log.e("dbg","click")
            Toast.makeText(holder.itemView.context,"This should be called",Toast.LENGTH_SHORT).show()
        }
    }

    override fun getItemId(position: Int): Long {
        return list[position].id
    }

    class TodoViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {


        fun bind(todoModel: TodoModel,pos:Int) {
            with(itemView) {
                txtShowTitle.text = todoModel.title
                txtShowTask.text = todoModel.description
                txtShowCategory.text = todoModel.category
                updateTime(todoModel.time)
                updateDate(todoModel.date)

            }

        }

        private fun updateTime(time: Long) {
            //4:55 AM
            val myformat = "h:mm a"
            val sdf = SimpleDateFormat(myformat)
            itemView.txtShowTime.text = sdf.format(Date(time))

        }

        private fun updateDate(time: Long) {
            //Mon, 5 Jan 2020
            val myformat = "EEE, d MMM yyyy"
            val sdf = SimpleDateFormat(myformat)
            itemView.txtShowDate.text = sdf.format(Date(time))

        }
    }

}

Any help would be appreciated.
