The Backbone.JS event on() method binds an event to an object and executes the callback when an event is fired.
Syntax:
object.on(event, callback, context)
Parameters:
event: This parameter is used to specify the event whose binding with an object is needed.
callback: This parameter is used to specify the callback function that will be executed when an event is fired.
