Error using EventEmitter api

[hightechlofi]

I am learning jsface, and have written a test class to debug the structure of how I want to write my classes before I code them full blown. Everything works great, unless I try to add EventEmitters to the object. I get the following error

f.updateConfig("new config"); ^ TypeError: Object [object Object] has no method 'updateConfig'

By event code is as follows:

var jsface = require("jsface"),
    Class = jsface.Class,
    extend = jsface.extend,
    b = require("bonescript"),
    util = require("util"),
    EventEmitter = require("events").EventEmitter;

var face = Class({

    constructor: function(opts, callback) {

      console.log("object created - " + opts);

      this.name = opts;

      //callback(null);

    },

    updateConfig: function(opts, callback) {

      console.log("config updated - " + opts);

      //callback(null);

    },

    setPower: function(power, callback) {

      console.log("set power - " + power);

      //callback(null);

    },

    setState: function(state, callback) {

      console.log("state set - " + state);

      //callback(null);
    },

    getData: function(callback) {

      console.log("data requested");

      callback(null, "data object");

    },

    getConfig: function(callback) {

      console.log("config requested");

      callback(null, "config object");

    },

    $statics: {

        actions: {

            subscribe: function() {

                console.log("subscribe called");

            },

            setState: function() {

                console.log("setState action called");

            },

            setPower: function() {

                console.log("setPower action called");

            },

            updateConfig: function() {

                console.log("updateConfig action called");

            },

            getConfig: function() {

                console.log("getConfig action called");

            }

        }

    }

});

module.exports = face;

//util.inherits(face, EventEmitter);

If I comment out the util.inherits line (as shown), I can access all of the class methods and everything works as expected (just no eventemitters). I have used this eventemitter api on non jsFace objects and it works well. Any ideas? Any alternatives to the EventEmitter?

Thanks.
