Backbone bootstrapped collection doesn't initialize correctly

Question

I have an issue, that was really hard to notice, because for the most part everything works. It was only when I tried to manipulate my data in my collections initialize func

Answer 1

You are bootstrapping incorrectly. You will need to use the Collection reset() method, and listen for a reset event in your collecton like so

Bootstrap code:

var collection = new MyCollection;
collection.reset();

Your collection code:

var MyCollection = Backbone.Collection.extend({
    model: MyModel,

    initialize: function() {
        this.on("reset", this.foobar);
    },

    foobar: function(collection) {
       console.log(this); // will be the same
       console.log(this.length); //  will equal 3
       this.each(function(model) {
           console.log(model); // will output a console for each model.
       });
    }

});
