code: function() {
        _.bindAll(this, 'addOne', 'addAll', 'render');
  
        this.input    = this.$("#new-todo");
  
        Todos.bind('add',     this.addOne);
        Todos.bind('refresh', this.addAll);
        Todos.bind('all',     this.render);
  
        Todos.fetch();
      }
docs: At initialization we bind to the relevant events on the `Todos` collection, when items are added or changed. Kick things off by loading any preexisting todos that might be saved in *localStorage*.
