How to unsubscribe the subscribed function in knockout?

var self = this;

var postbox = new ko.subscrib

Store results of call to subscriptions in a variable (or, in your case, in an array).

When you want to unsubscribe, simply call dispose on each subscription.

Fully described here - http://knockoutjs.com/documentation/observables.html

Your code will look like this:

//store subscriptions in array
var subscriptions = [];

for ( var i in myViewModel ) {
    var model = myViewModel[i];
    subscriptions.push(model.subscribe( self.notifyChange.bind( model, i ) ));
}


//unsubscribe
for(var i in subscriptions) {
    subscriptions[i].dispose(); //no longer want notifications
}
