How to Fire Personal Event in Javascript

Question

I can't fire personal events using Javascript in IE. In Firefox work great.

My code is:

var evento; 
if(document.createEventObject)  
{  
   evento = document.createEventObject();  
   document.fireEvent('eventoPersonal', evento);     
}  
//FF  
else  
{  
    evento = document.createEvent('Events');  
    evento.initEvent('eventoPersonal',true,false);  
    document.dispatchEvent(evento);  
}

But when try to execute document.fireEvent('eventoPersonal', evento); in IE, it doesn't work. How can I fire NO custom events in IE?

In Internet Explorer I get the error: "Invalid arguments" in the line where execute document.fireEvent('eventoPersonal', evento);

Dean Edward's describes how to fire cutsom events in IE

http://dean.edwards.name/weblog/2009/03/callbacks-vs-events/

Its near the bottom of the article

var currentHandler;

if (document.addEventListener) {

  // We've seen this code already

} else if (document.attachEvent) { // MSIE

  document.documentElement.fakeEvents = 0; // an expando property

  document.documentElement.attachEvent("onpropertychange", function(event) {
    if (event.propertyName == "fakeEvents") {
      // execute the callback
      currentHandler();
    }
  });

  dispatchFakeEvent = function(handler) {
    // fire the propertychange event
    document.documentElement.fakeEvents++;
  };
}
