Unable to add custom properties to listeners in controllers

Build: 678

It's currently not possible do the following code using Architect:

Code:

---

Ext.define('app.controller.myController', {
    init: function() {
        this.control({
            'form #textfield': {
                change: {
                    fn: this.textFieldChange,
                    buffer: 500 // Delay the request by half a second
                }
            }
        })
    },
//...
    }
});
