extjs 4- Radiogroup值

Question

我不知道如何设置我的radiobutton组的值。价值＆＃39; GP＆＃39;或者＆＃39; P＆＃39;在表格中列出＆＃39; listSites＆＃39;

以下是代码：

for (i = 0; i < me.dataSite.length; i++) {
            siteName = me.dataSite[i].name;// data site is a table of object site with his id and name.
            idSite = me.dataSite[i].id;
            Type = me.listSites['site' + idSite]; // listSite is a table that contains the type of site it takes the value 'P' or 'GP'
            itemsArray.push(
                {
                    xtype: 'radiogroup',
                    fieldLabel: siteName,
                    labelWidth: me.defaultLabelWidth,
                    width: '100%',
                    border: false,
                    defaults: {
                        padding: '0 20 0 0',
                        xtype: 'radio',
                        name: 'listSite' + idSite,
                        value: Type // here's the problem
                    },
                    layout: 'hbox',
                    items: [
                        {
                            boxLabel: ressources.RadioGroupeProduitBoxLabel,
                            inputValue: 'GP'
                        },
                        {
                            boxLabel: ressources.RadioProduitBoxLabel,
                            inputValue: 'P'
                        }]
                }
            );
        }
