A select with marionette JS ?

select.js.coffee

ES.module 'Views', (Views, App, Backbone, Marionette, $, _)->
  class Views.Select extends Marionette.ItemView
    template: JST['select']
    ui:
      select: 'select'
    events:
      'change select': 'selected'
    initialize: (options)->
      @listenTo @model, 'reset', this.display, this
      @selected = options.selected
    display: ()->
      this.ui.select.find('option').remove()
      this.ui.select.append("<option value=''-> Pick one</option>")
      for opt in @model.models
        this.ui.select.append("<option value='#{opt.get('_id')}'>#{opt.get('name')}</option>")

And more simplicity:

events:
      'change select': '_selected'
    initialize: (options)->
      @listenTo @model, 'reset', this.display, this
      @selected = options.selected
    _selected: (event)->
      @selected $('select').val()

Usage

ES.Views.new(
  model: @aCollection,
  select: (id) ->
     alert id
)
