Notifications in on_change method

Hello, I would like to implement a notification like "Globe" (as it appears when required fields are empty and placed [the Following fields are invalid:]) in a method on_change. Examining the code openERP only found a place where was implemented this type of message (addons / web / static / src / js / view_form.js: 867). I ask, you can use this notification type for a method on_change?.
