How to perform click on button of ListView element in Android

I have listView and each element contains 1 button

When user presses some element of ListView (but not button) it works correctly and android shows toast: "Not button clicked, $position works correctly"

But I also need to make toast (and get position of button) when button is clicked in specific listView element. I tried to use view.imageViewButton.setOnClickListener inside of listV.setOnItemClickListener but in this scenario button worked only after I clicked a blank space to the left of the button.

listV.setOnItemClickListener { parent, view, position, id ->  //I tried you use comented line to solwe my problem  //view.imageViewButton.setOnClickListener { Toast.makeText(this, "button $position is clicked",Toast.LENGTH_SHORT).show() }  Toast.makeText(this, "not button clicked, works correctly", Toast.LENGTH_SHORT).show()} 

How should I do to activate buttons when onCreate(savedInstanceState: Bundle?) starts?

My kotlin code:

class MainActivity : AppCompatActivity() {override fun onCreate(savedInstanceState: Bundle?) {    super.onCreate(savedInstanceState)    setContentView(R.layout.activity_main)    var db = DataBaseHelper(this)    var cursor = db.returnLines()    listV.adapter = SimpleCursorAdapter(this,        R.layout.view_holder,        cursor,        arrayOf("imia"),        intArrayOf(R.id.listNameView),        0)    listV.setOnItemClickListener { parent, view, position, id ->      //I tried you use comented line to solwe my problem      //view.imageViewButton.setOnClickListener { Toast.makeText(this, "button $position is clicked",Toast.LENGTH_SHORT).show() }      Toast.makeText(this, "not button clicked, $position works correctly", Toast.LENGTH_SHORT).show()    }}
