        var radioItems = this.data.radioItems;
        for (var i = 0, len = radioItems.length; i < len; ++i) {
            radioItems[i].checked = radioItems[i].value == e.detail.value;

        for (var i = 0, lenI = checkboxItems.length; i < lenI; ++i) {
            checkboxItems[i].checked = false;
            for (var j = 0, lenJ = values.length; j < lenJ; ++j) {
                if(checkboxItems[i].value == values[j]){
                    checkboxItems[i].checked = true;
