extjs gridpanel属性设置，请大神指点

Question

applyAccount.gridManager = new Ext.grid.GridPanel({
//title : '客户经理选取列表',
store : applyAccount.storeManager,
colModel : applyAccount.colModelManager,
bbar : applyAccount.CusBbar,
selModel : applyAccount.CusSelModel,
columnLines : true,//否显示列分割线，默认为false
autoScroll : 'auto',
autoSizeColumns : true,//根据列内容自动适应列宽度
viewConfig : {

forceFit : true
},

loadMask : true,
tbar : [

'客户经理编号：',{
　 id　:　'ManagerNumP',
xtype　:　'textfield'},'-',
{
　　　　　　　　　　　 text　:　'查询',
iconCls : 'query',
handler : function()　{
applyAccount.storeManager.load({

params: { start: 0,
limit: applyAccount.CusPageSize,
level:2,
managerNum:Ext.get('ManagerNumP').dom.value
},
callback:function(store,resc){
var record2 = applyAccount.grid.getSelectionModel().getSelected();
if(record2){
var records = new Array();
applyAccount.storeManager.each(function(record){
if(record.data.account == record2.data.clientManagerNum){
records.push(record);
}
});
applyAccount.CusSelModel.selectRecords(records,true);
}
}

});
}
}]
});
这里面的id怎么设置成动态的呢？不是写死的这种

     var domID = 'ManagerNumP';//////////////修改这个变量
    applyAccount.gridManager = new Ext.grid.GridPanel({
        //title : '客户经理选取列表',
        store: applyAccount.storeManager,
        colModel: applyAccount.colModelManager,
        bbar: applyAccount.CusBbar,
        selModel: applyAccount.CusSelModel,
        columnLines: true,//否显示列分割线，默认为false
        autoScroll: 'auto',
        autoSizeColumns: true,//根据列内容自动适应列宽度
        viewConfig: {

            forceFit: true
        },

        loadMask: true,
        tbar: [

        '客户经理编号：', {
            id: domID,//////////////
            xtype: 'textfield'
        }, '-',
        {
            text: '查询',
            iconCls: 'query',
            handler: function () {
                applyAccount.storeManager.load({

                    params: {
                        start: 0,
                        limit: applyAccount.CusPageSize,
                        level: 2,
                        managerNum: Ext.get(domID).dom.value////////////////
