The message event interface has been updated. The initMessageEvent method no longer exists. Look here at bottom of the thread. According to that body of your onload function should be:

var event = new MessageEvent('callMe', { 'view': window, 'bubbles': false, 'cancelable': false, 'data': 'some data' });
document.dispatchEvent(event);

Hope this helps.
