addAllFoo:sta kun kutsutaan, niin this.somProperty.doSOmething() feilaa, koska "window" -objektilla ei ole propertya "someProperty"

foo.js

window.FooModel = Backbone.Model.extend({});
window.FooCollection = Backbone.Collection.extend({});
window.Foos = new FooCollection;

window.FooView = Backbone.View.extend({
  someProperty: <something>,
  initialize: function() {
    Foos.bind('add', this.addFoo, this);
    Foos.bind('reset', this.addAllFoos, this);
    Foos.fetch();
  },
  addFoo: function(model) {
     this.someProperty.doSomething();
     //add to dom
  },
  addAllFoos: function() {
     Foos.forEach(this.addFoo);
  }
});
window.App = new FooView;
