Not able to see any data in this list
Any guess why it is not working

Code:
Ext.define("StockWatch.view.MarketList", {    extend: "Ext.dataview.List",
	requires: "Ext.plugin.PullRefresh",
    xtype: "marketlist",
    config: {
        loadingText: "Loading Markets...",
		layout: 'fit',
		plugins: [
            {
                xclass: 'Ext.plugin.PullRefresh',
            }
		],
		store: {
			fields : ['CompanyCode','LastTradedPrice'],
            proxy : {
				type:'jsonp',
                url:'http://money.rediff.com/money1/current_status_new.php?companylist=17023928%7C17023929&id=1354690151&Rand=0.6305125835351646',
				callbackKey: 'callbackJsonp',
                reader: {
					type: 'json',
					rootProperty: ''
                }
            },
            autoLoad:true,
        },
        emptyText: '</pre><div>No markets found.</div><pre>',
        onItemDisclosure: false,
        itemTpl: '</pre><div>{CompanyCode}</div><div>{LastTradedPrice}</div><pre>',
    }
});
