Individual ListView scrolling randomly changes button text or edittext

I searched for this, but to no avail. I did not get an exact answer to the question.

I have a button inside ListView, when this button is pressed, it shows a warning dialog to select a date and after selecting a date, the selected date will be a text button. The code works fine, but when I scroll down and up, the date will randomly change here is my code for the method of getView()my adapter. This also happens with EditTextwhen I click any of EditTextworks fine, but when I start scrolling, the values ​​also change.

Here is my view method

public View getView(int position, View convertView, ViewGroup parent) {
    final ViewHolder viewHolder;
    if(convertView == null){
        convertView = layoutInflater.inflate(R.layout.repeat_entry_listview,null);

        viewHolder = new ViewHolder();
        viewHolder.btnDate = (Button) convertView.findViewById(R.id.rpbtnDate);
        viewHolder.txtNotes  = (EditText) convertView.findViewById(R.id.rpNotes);
        convertView.setTag(viewHolder);
    }else{
        viewHolder = (ViewHolder) convertView.getTag();
    }


    RepeatEntryList repeatEntryList = listData.get(position);
    viewHolder.btnDate.setText(repeatEntryList.getDate());
    viewHolder.btnDate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          //EVEN IF I REMOVE THE CODE FOR SETTING THE BUTTON TEXT TO JUST LIKE THE BELOW CODE. SCROLLING ISSUES STILL PERSIST

          viewHolder.btnDate.setText("just sample date text");

            //**NOTE UPDATED**
            //MY EDITTEXT ALSO HAVE THE SAME BEHAVIOR
        }
    });
    viewHolder.txtNotes.setHint(contx.getResources().getString(R.string.placeholder_txt));
    return convertView;
}
