+	 * there. This method will attach the following event listeners to the observable:
+	 *
+	 * - 'update'       (gets called by R::store, before the records gets inserted / updated)
+	 * - 'after_update' (gets called by R::store, after the records have been inserted / updated)
+	 * - 'open'         (gets called by R::load, after the record has been retrieved)
+	 * - 'delete'       (gets called by R::trash, before deletion of record)
+	 * - 'after_delete' (gets called by R::trash, after deletion)
+	 * - 'dispense'     (gets called by R::dispense)
+	 *
+	 * For every event type, this method will register this helper as a listener.
+	 * The observable will notify the listener (this object) with the event ID and the
+	 * affected bean. This helper will then process the event (onEvent) by invoking
+	 * the event on the bean. If a bean offers a method with the same name as the
+	 * event ID, this method will be invoked.
