KineticJS - basic javascript scope issue

Ok, I'm trying to put the javascript in a separate source file. This is a newbie question, but I'm getting an 'undefined' error on layer.add(imageObj). I'm guessing it's because of window.onLoad, but I didn't find an immediate answer.

<html>
<head>
    <link rel="stylesheet" type="text/css" media="screen" href="index.css">
    <script type="text/javascript" src="js/kinetic-v5.1.0.min.js"></script>
    <script type="text/javascript" src="js/game.js" defer="defer"></script>
</head>
<body>
    <div id="board"></div>
</body>

The javascript:

window.onload = function(){

var stage = new Kinetic.Stage({
    container: 'board'
});
var layer = new Kinetic.Layer();

var imageObj = new Image();
imageObj.onload = function() {
  var image = new Kinetic.Image({
    x: 0,
    y: 0,
    image: imageObj,
    width: 100,
    height: 100
  });
};
imageObj.src = 'resources/map.jpg';

layer.add(imageObj);
stage.add(layer);
};

You need to add into layer Kinetic.Image instance (image in your source) not imageObj. You can do this in onload function. See: http://jsbin.com/buroyi/2/edit
