KotterKnife - cannot use bindView(R.id.example_id) for some classes

I am getting the below error when trying to use KotterKnife - but only for some classes. What's going on? 

e: /Users/user/dev/git/to14/android/src/main/kotlin/com.example/adapters/ChapterListAdapter.kt: (59, 34): Unresolved reference. None of the following candidates is applicable because of receiver type mismatch: 
public fun <T : android.view.View> android.app.Dialog.bindView(id: kotlin.Int): kotlin.properties.ReadOnlyProperty<kotlin.Any, android.widget.TextView> defined in butterknife
public fun <T : android.view.View> android.support.v4.app.Fragment.bindView(id: kotlin.Int): kotlin.properties.ReadOnlyProperty<kotlin.Any, android.widget.TextView> defined in butterknife
public fun <T : android.view.View> android.app.Fragment.bindView(id: kotlin.Int): kotlin.properties.ReadOnlyProperty<kotlin.Any, android.widget.TextView> defined in butterknife
public fun <T : android.view.View> android.view.ViewGroup.bindView(id: kotlin.Int): kotlin.properties.ReadOnlyProperty<kotlin.Any, android.widget.TextView> defined in butterknife
public fun <T : android.view.View> android.support.v7.widget.RecyclerView.ViewHolder.bindView(id: kotlin.Int): kotlin.properties.ReadOnlyProperty<kotlin.Any, android.widget.TextView> defined in butterknife
public fun <T : android.view.View> android.app.Activity.bindView(id: kotlin.Int): kotlin.properties.ReadOnlyProperty<kotlin.Any, android.widget.TextView> defined in butterknife

Kotterknife's bindView delegate will work only on sublclasses of Activity, Dialog, ViewGroup, Fragment, the support library Fragment, and recycler view's ViewHolder. I guess you're trying to bind view as property of ListAdapter, but to have it work you'll have to have object on which you could call findViewById.

For non-RecyclerView ViewHolder you can try

class ViewHolder(view: View) { 
    val textView: TextView = view.findViewById(R.id.name) as TextView 
}
