					height: "300",
					width: "450",
					position: { my: "left bottom", at: "right top", of: elem},
					buttons: {
						"Save": function() {
							var txt = $('textarea', this).val();
//			Put the editied note back into the data area of the element
//			Very important that this step is included in custom callback implementations
							$elem.data("note", txt);
							$(this).dialog("close");
						},
//						"Delete": function() {
//							$elem.trigger("remove");
//							$(this).dialog("close");
//						},
                                                "Add Comment": function(e){
