jquery variable not changing in url while using easyscroll
===

The $catcount remains the same while passing, eventhough it chnages its value , the url sends the same old value 

    <script type="text/javascript">
    	var $catcount=1;
    	jQuery(document).ready(
    		function() {
    
    			jQuery('.scroll_container').scrollExtend(
    				{	
    					'target': 'div#scroll_items',			
    					'url': 'populates.php', 
    					'newElementClass': 'list_item more_content',
    		'ajaxSettings': {'data':'cid='+$catcount},
    					'onSuccess':function(){jQuery('.scroll_container').scrollExtend('enable');$('#fe').html("");$catcount++;alert($catcount);} 
    
    				}
    			);
    			
    		}
    	);
       </script>
