BooksAdapter adding click listener

BooksAdapter.kt

override fun onBindViewHolder(holder: DataBindingViewHolder<Listable>, position: Int) {
    super.onBindViewHolder(holder, position) // make sure you keep this
    
    holder.itemView.setOnClickListener {
      // whatever you want!
      // you could add a Presenter/ViewModel to the Adapter constructor and call a method, for instance:
      // viewModel.onItemClicked()
    }
}
