Событие изменения колонки

Создал замещающий модуль на страницу редактирования контакта, на булевскую колонку.

Подскажите может я не так делаю что.

При изменении значения получаю ошибку в консоли:

define("ContactPageV2", [], function() {
	return {

				var isKeyContact = this.get("UsrIsKeyContact");
				this.log(isKeyContact);
