jqgrid导出不导出正确的数据

Question

when I export jqgrid to excel, I am not getting expected result. I am getting right data for two columns and for the rest columns it says undefined, also I am getting two extra columns at the end (please see the attached pic). I am using same export function for other jqgrid and I am getting right output there. I don't understand why I am getting this kind of result for this jqgird. I already spent more than 2 days on this but can't output right result. Any help will be highly appreciated.

 $("#dataTable").jqGrid({ url: '/test/getAllData.html', datatype: "json", colNames: ['id', 'Material name', 'Unit', 'Supplier', 'Date', 'Amount'], colModel: [ { name: 'id', index: 'id',width: 300 }, { name: 'MaterialName', index: 'MaterialName', width: 300 },, { name: 'unit', index: 'unit', width: 300 }, { name: 'supplier', index: 'supplier', width: 300 }, { name: 'date', index: 'date', width: 300 }, { name: 'amount', index: 'amount', width: 300 } ], rowNum: 100, rowList: [25, 50, 75, 100], pager: '#dataTablePager', viewrecords: true, ignoreCase: true, loadonce: false, viewrecords: true, jsoonReader: { repeatitems:false; }, loadComplete : function () { exportToExcel("dataTable"); //export function } });

 <div id="dataTable"/> </div id="dataTablePager"/>

There was some issues on export js function , export js function was setting colmodels manually with different names so I was getting undefined. I have fixed this issue
