can we use of $this in closure for jquery plugin

Question

I tried creating a quick tooltip plugin using the jquery and jquery ui position. Is the way I have used the enclosure are right and is the use of position right since in ff it seem to have some memory problem..it remembers the previous position when I refresh the page after the first time. below is the code

This need the latest jquery & jquery ui

 $.fn.tooltip = function(options) {
 var defaults = {
 my : "left center",
 at : "right top",
 collision : "none",
 offset : "0 0"
 }
 var options = $.extend(defaults, options);
 return this.each(function() {
 var $this = $(this);
 var tip = $("<span class='tooltip'>" + $this.attr('tooltip') + "</span>");
 tip.css({
 width : options.width
 });
 $this.after(tip);
 tip.position({
 my : options.my,
 at : options.at,
 of : $this,
 collision : options.collision,
 offset : options.offset
 });
 $this.add(tip).hover(function() {
 var timeoutId = $this.data('timeoutId');
 if(timeoutId) {
 clearTimeout(timeoutId);
 }
 tip.fadeIn("slow");
 }, function() {
 var timeoutId = setTimeout(function() {
 tip.fadeOut("slow");
 }, 650);
 $this.data('timeoutId', timeoutId);
 });
 });
 };
 $(function() {
 $('#input1').tooltip();
 $('#input2').tooltip();
 });

css style

 .tooltip {
 display: none;
 position: absolute;
 background-color: #ffaa5e;/* #F5F5B5; */
 border: 1px solid #DECA7E;
 color: #303030;
 font-family: sans-serif;
 font-size: 12px;
 line-height: 18px;
 padding: 10px 13px;
 position: absolute;
 text-align: center;
 top: 0;
 left: 0;
 z-index: 3;
 }

Try this type of closure

 $this.add(tip).hover(function() {
 return function() {
 var timeoutId = $this.data('timeoutId');
 if(timeoutId) {
 clearTimeout(timeoutId);
 }
 tip.fadeIn("slow");
 };
 }(), function() {
 return function() {
 var timeoutId = setTimeout(function() {
 tip.fadeOut("slow");
 }, 650);
 $this.data('timeoutId', timeoutId);
 };
 }());

Just dont forget to tell if it solves the problem. Good luck.
