# WP 2.8: Widget Admin Backend

 * I have two odd programming-problems with the new widget backend:
    1. WP_Widget-
   >form($instance): I want to use JQuery-Event Listener in my widget form. But 
   it only works, after I saved the widget on sidebar. When I drag & drop the widget
   on sidebar (without saving), the jQuery-Listener seems not to be bind. [maxchirkov have the same problem](http://wordpress.org/support/topic/224591)
   2. WP_Widget->update($new_instance, $old_instance): This is really odd. When 
   I use this code ($template_save is a parsed xml file): `$instance['above_html']
   = $template_save->AboveHtml;` $instance[‘above_html’] is empty. But when I use
   this code `$instance['above_html'] = "".$template_save->AboveHtml;` it works…
 * Thanks for your reply!

 * #1 is resolved:
    Use JQuery [live](http://docs.jquery.com/Events/live).
 * Für Deutschsprechende: In [meinem Blog](http://www.freakcommander.de/2138/computer/jquery-event-listener-fuer-hinzugefuegten-inhalt/)
