Batmanjs Model attribute reader

Given the following js model:

class MyApp.Post extends Batman.Model
  @encode options

Given the server side json (generated with rabl):

object @post
attributes :id, :category
node(:categories) {
  Category::OPTIONS...

To inspect a model attributes binded to a dom element
$context($("#elem-id")[0]).controller.model_name.toJSON()

Original idea taken from the link below.

class App.AutocompleteView extends Batman.View
  html: "<input type='text' />"
  autocompleteSource: -> []
  viewDidAppear: ->
    # I had to replace @node (as it is in the official documentation) to @node.firstChild since that...
