How to listen to the subscriptions?

[RupikaSahu]

Hi,

I am able to call methods to server and get the data. But how should I listen to the subscriptions? When server sends an update, do we need to listen them through notifications or do we need to check the Meteor database and it's collections? If we need to listen through notifications. I'm using "lists_changed"(underscore and action name as format) as Notification name. Is this the correct format ?

Any reply would be a great help. Thank you :).
