controller.coffee

define ->
    class OrderInfoController

        getSource: ->
            source = 
                id: "1"
                location: "Rome"

            return source

orderSpec.coffee

define ->

    $plugins: [
        'wire/debug'
        'wire/on'
        'wire/dom'
        'wire/dom/render'
        'cola'
    ]

    orderInfoModel:
        create:
            module: 'cola/Model'
        ready:
            "addSource": {$ref: "controller.getSource"}

    controller:
        create: "components/myComponent/controller"

Strange, but this code does not work.
