Backbone error, Object add has no method 'bind'

items.bind 'add', (item) => 
    @addOne(item)

addOne: (item) ->
    view = new ListItem({model: item})

..initialization of the view throws this error: TypeError: Object add has no method 'bind'

class ListItem extends Backbone.View

    el: $ '#wrap'

    template: $ '#listItem'

    initialize: () ->
        @model.bind 'change', @render, @ 
        @model.bind 'destroy', @remove, @

    render: () ->
        @el.append @template.tmpl @model.toJSON()

EDIT: logging item before setting the view results in...

I开发者_开发百科tem
_callbacks: Object
_changed: false
_changing: false
_escapedAttributes: Object
_previousAttributes: Object
attributes: Object
cid: "c2"
collection: Items
__proto__: ctor

but if I log @model when initializing the view it's an empty object called add

EDIT 2: item.bind is undefined from within addOne, not sure why though

Your code looks fine, but the object that you've added to items doesn't appear to be a valid model. What code are you using for your items.add call? Verify that you don't get an error when you run items.add(new Backbone.Model).

Perhaps you did

items.add [{foo: bar}]

but set the model property on the Collection class that items is an instance of to something other than a Backbone.Model subclass?
