    event.data = { oldName: oldName };

var MyClass = function () {};
MyClass.prototype.sayHello = function () {};

Koine.Publisher.wrap(MyClass);

var object = new MyClass();

object.on('sayHello', function (e) {
    alert(['Hello', e.name].join(' '), '!');
});


var event  = new Koine.Publisher.EventType("sayHello");
