How to use adsense after some time of page load
===

I've created a little social networking website which is working fine, 
but in wall page google ads is not showing,
its showing and working fine in other pages 
but in wall page not showing because the page content is showing with js

So i think there's a problem of keywords and description issue

i just want to know how to use google ads after sometime 

i try 

    function show(){
    //My Adsense Code But Still Not Working
    }
    
    setTimeout('show()',5000);
