featherjs callback is undefined

Question

I'm trying to use feathersjs, but I can't get past the sample programs (the todo list on the feathers.js main site). The only thing that gets passed into the functions is the received data. param and callback are always undefined.

var myService = {
  find: function(params, callback) {},
  get: function(id, params, callback) {},
  create: function(data, params, callback) {},
  update: function(id, data, params, callback) {},
  patch: function(id, data, params, callback) {},
  remove: function(id, params, callback) {},
  setup: function(app, path) {}
}

What am I doingn wrong? do I need to use an older version? I'm currently using "latest" for feathers in my package.json

Edit:

I quite literally copy-pasted the example code from http://feathersjs.com/#documentation

Edit: Source files added:

// app.js
var bodyParser = require("body-parser");
var compression = require("compression");
var express = require("express");
var feathers = require("feathers");
var http = require("http");
var io = require("socket.io");

var v1 = require("./lib/v1");
var config = require("./lib/config");

var app = feathers()
    .configure(feathers.socketio())
    .use(bodyParser.json())
    .use("/v1", v1)

var port = process.env.PORT || 3000;
app.listen(port);

and

//lib/v1.js
var v1Service = {
    find: function(params, callback) {
        console.log("finding");
        callback(null, [{
            "uuid": "blahblahblah"
        }]);
    },
    get: function(id, params, callback) {
        console.log("geting");
        callback(null, {
            "uuid": "blahblahblah"
        });
    },
    create: function(data, params, callback) {
        console.log("creating, args:" + JSON.stringify(callback));
        callback(null, {
            "uuid": "blahblahblah"
        });
    },
    update: function(id, data, params, callback) {
        console.log("updating");
        callback(null, {
            "uuid": "blahblahblah"
        });
    },
    patch: function(id, data, params, callback) {
        console.log("patching");
        callback(null, {
            "uuid": "blahblahblah"
        });
    },
    remove: function(id, params, callback) {
        console.log("removeing");
        callback(null, {
            "uuid": "blahblahblah"
        });
    },
    setup: function(app, path) {
        console.log("setup");
    }
}

module.exports = v1Service;

The problem was in my client-side javascript. I was using "emit" incorrectly:

var sock = io.connect();
sock.emit("v1::create", {"some":"data"})

The above javascript is incorrect. Two additional parameters need to be supplied:

var sock = io.connect();
sock.emit("v1::create", {"some":"data"}, {}, function(){ console.debug("IN CALLBACK") })

I didn't think the problem would be from the client-side code, but it is
