Problems with dynamically adding views in Kotlin

I want to edit the text of the view that is created every time a button is pressed. However, when running in the app, the text is only modified in the first and last (nth) views, and the second and n-1 views do not change.enter image description here I uploaded a picture showing my current situation.

MainActivity.kt

package com.akj.my_text_rec
import android.content.Context
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.widget.LinearLayout
import androidx.appcompat.app.AppCompatActivity
import kotlinx.android.synthetic.main.activity_main.*
import kotlinx.android.synthetic.main.field.*

class MainActivity : AppCompatActivity() {


    private var parentLinearLayout: LinearLayout? = null


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)


        //title = "KotlinApp"
        parentLinearLayout = findViewById(R.id.parent_linear_layout)


        adkishw.setOnClickListener{
            onAddField()
        }


    }
    fun onDelete(view: View) {
        parentLinearLayout!!.removeView(view.parent as View)
    }

    fun onAddField() {
        val inflater =
            getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
        val rowView: View = inflater.inflate(R.layout.field, null)
        parentLinearLayout!!.addView(rowView, parentLinearLayout!!.childCount - 1)
        number_edit_text.setText("asdf")

    }
}

field.xml

<?xml version="1.0" encoding="utf-8"?>
