Registering events within an object

Registering events within an object

I'm having a hard time figuring out how to refer to an object while inside a jquery event function. In the following example, "this" at first is referenced as #myDiv. But inside the draggable event, "this" refers to something else. I am not sure what it is referring to, but how do I reference the original object (Human) from within this event?
  1. var Person = new Human("#myDiv", "my data");

  3. function Human(element, myName) {
  4.   this.name = myName;
  5.   $(element).draggable({
  6.    start: function() { alert(this.name); }
  7.   });
  8. }
