SirTrevor.Blocks.Gallery = do ->
  SirTrevor.Block.extend
    _initialized: no
    initializeUploader: ->
      return if @_initialized
      @uploader = @getTextBlock().find('@uploader')
      @uploader.fileupload ((->
        debugger
        url: '/photos.json'
        type: 'PATCH'
        dataType: 'json'
        done: (e, data) ->
          console.info(data)
        formData: =>
          debugger
      ).bind(@))()

      @_initialized = yes

так нужно делать:

      @uploader = @getTextBlock().find('@uploader')

      @uploader.fileupload
        url: '/photos.json'
        type: 'PATCH'
        dataType: 'json'
        done: (e, data) ->
          console.info(data)

      @uploader.bind 'fileuploadsubmit', ((trevor) -> (e, data) ->
        data.formData = { gallery_key: trevor.galleryId() }
      )(@)
