How to use TextWatcher for more than one EditText?

kotlin-textwatcher.md

val textWatcher = object : TextWatcher {
    override
    fun beforeTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2:Int) {

    } 

    override
    fun onTextChanged(charSequence: CharSequence, i: Int, i1: Int, i2: Int) {

    }

    override
    fun afterTextChanged(editable: Editable?) {
        if (editable != null && !editable.toString().equals("")) {
            // Checking editable.hashCode() to understand which edittext is using right now
            if (editText.editText!!.text.hashCode() === editable.hashCode()) {
                // This is just an example, your magic will be here!
                val value = editable.toString()
                editText.editText!!.removeTextChangedListener(this)
                editText.editText!!.setText(value)
                editText.editText!!.addTextChangedListener(this)
            }
        } else if (editText2.editText!!.text.hashCode() === editable!!.hashCode()) {
            // This is just an example, your magic will be here!
            val value = editable!!.toString()
            editText2.editText!!.removeTextChangedListener(this)
            editText2.editText!!.setText(value)
            editText2.editText!!.addTextChangedListener(this)
        }
    }
}

Disculpa cuando trato de hacer la implementacion, no me permite utilizar el editText.editText !!

mi codigo lo tengo de la siguiente manera txt_importe.editText!!.text.hashCode() === s.hashCode()
