gistfile1.js

function MyObject(){
  this.button = document.getElementById("myButton");
  var workAroundTheClosure = this;
  this.button.addEventListener('click', function(){
      workAroundTheClosure.buttionClick();
    }, 
  false);
}

MyObject.prototype.buttonClick = function(){
  console.log("it works!");
  //at least in chrome I've also been able to get at the event object...cool!
  console.log(event.target.id);
}
