ext js STORE LOAD EVENT

Hi,

Code:

       me.store = Ext.create('Ext.data.Store', {
            pageSize : parseInt(info.PageSize),
            groupField: info.GroupBy,
            fields: storeFields,
            idProperty: 'Id',
            noCache: true,
            proxy : {
                type: 'ajax',
                url: info.Url,
                reader: {
                    type: 'json',
                    root: 'Rows',
                    totalProperty: 'totalCount'
                }
            }
        });

this code can load data. but on load event

Code:

        
me.store.on('load', function (sender, recs, opt) {                        if (component.loadStore != undefined) {
                component.loadStore(sender, recs, opt);
            }
     }, component);

sender.data.items is empty. sender.data.autoSource.items is full.

what can i do
