Question

I am using Backbone.Marionette for my project .I had scenario where i want a custom method to be executed when a model in added in collection.Since i am using collection view and i noticed that Marionette itself does a lot of stuff (like appending content of newly added item and binding to ‘all’ event etc) So how can i add my own functionality without missing what marionette has to offer.

Answer 1

Marionette has some special bindings for collection and models (ItemView Docs).

So I think you can just add something like that to your view:

collectionEvents: {
    "add": "on_add"
},

on_add: function(){
     //Your logic here
}
