ext里复选框里的值的显示问题

ext里用updateRecord(做修改)之后,复选框的数据在grid里显示的不是之前inputvalue里的值而是true和false,不是inputvalue的问题,求大神解决一下。

附上代码:

Ext.define('Writer.Form1', {
extend: 'Ext.form.Panel',
alias: 'widget.writerformupd',
initComponent: function(){
this.addEvents('create');
Ext.apply(this, {
activeRecord: null,
iconCls: 'icon-user',
frame: true,
title: 'User -- All fields are required',
defaultType: 'textfield',
bodyPadding: 5,
fieldDefaults: {
anchor: '100%',
labelAlign: 'right'
},
items: [{
fieldLabel: '编号',
name: 'userId',
allowBlank: false
}, {
fieldLabel: '姓名',
name: 'uname',
allowBlank: false
}, {
xtype:'numberfield',
fieldLabel: '身高',
name: 'height',
width: 180,
decimalPrecision: 1,
minValue: 0.01,
maxValue: 200,
unitText: ' cm',
allowBlank: false,
blankText: '请输入身高'

            }, {
                xtype:'datefield',
                fieldLabel: '出生日期',
                name:'birthday',
                format: 'Y-m-d',
                editable: false,
                allowBlank: false,
                blankText: '请选择日期'
            }, {        xtype:"fieldcontainer",
                layout:"hbox",
                fieldLabel:'性别',
                defaults: {
                    flex: 1
                },
                items:[{
                    xtype:"radio",
                    boxLabel:"男",
                    name:'sex',
                    inputValue:'男',

                    name:'sex',
                    inputValue:'女',
                }]

            }, {
                layout:'hbox',
                defaults: {
                    flex: 1
