[SalesForce] Onblur issue on text box autocomplete..

I have a VF page..I have a button open pop up..on click of that button i am opening a pop up using output panel and css…using the code something like this..

On that pop up i am using autocomplete using VF remoting and a confirm button on that popup..My problem is i am using blur event whenever i type some thing in that autocomplete text box i am selecting a autocomplete record and on onblur event calling a method but the curser remains in that text box.So when i click a confirm button onblur event is again called calling the controller method.

I want the curser to move out of the textbox after onblur event ..?? I need some jquery/javascript code…

close: function(){
      j$(esc('{!autocomplete_textbox}')).blur();
   }

Please help i am stuck with this issue…for 3 days…

Thanks
