function Foo() {
 this.bar = false;
}

Foo.prototype={
 onLoad: function() {
          this.bar=true;
         },

 create: function(id) {
          SomeClass.someMethod({
           id: id,
           onWorkIsDone: this.onLoad
          });
         }
};

var temp=new Foo();
temp.create();

This sample has a logic error in string 'onWorkIsDone: this.onLoad'. What I have to place instead of 'this.onLoad' to make SomeClass call exactly the temp.onLoad method when it finishes it's work?
