reload scripts of controls with change visibility

i have a control that has some checkboxes and some javascript functions. i use it in s开发者_StackOverflow中文版ome pages and it work correctly. in one case, i use it in a page that have two table and table that has this control in pageload is invisible and after some operation, i change its visibility TRUE. but scripts of control don't load, and i have error on this page : 'Object expected'. in source, there are not scripts of control. how can i reload scripts of control after change visibility?

my control was in a table that i changed visibilty with mytable.visible = false; or mytable.visible = true. on page_load mytable's visible = false and scripts of control dont load. then when i change visiblility , its scripts don,t load. Now i change visibility by style='display:none' or style='display:block'. In this case scripts of control load on page_load.
