sencha touch list分页

/**  
 * @Author sai  
 *  
 */
Ext.define('SmartMenu.store.NewsStore',
{
	extend:'Ext.data.Store',
	config:
	{   
		model:'SmartMenu.model.News',
		newsNum:'0',
		autoLoad: true,
		 pageSize: 4,
		 proxy: {
 	        type: 'jsonp',
 	        url: 'http://192.168.1.126:8093/Serv/PhoneServHandler.ashx',
 	        callbackKey: 'callback',
 	        pageParam:'pageIdx', //页码
 	        limitParam:'pageSize',//页数
 	       extraParams:{req:'GetNewsReport'},

 	        reader: {
 	          type: 'json',
 	          rootProperty: 'items'
 	      },
 	    },
       	} 
});
		

		

在 list 视图上 加上这个 config:{ limit: 4, plugins: [{ xclass: 'Ext.plugin.ListPaging',autoPaging: true}]};
