Error while binding json - json

Question

I am using Angularjs in one of my programme. I am using it to add items to a json array. Then I save this array to a temporary file. Programme is working fine upto this time. When I try to bind saved json string to table I get error Error: [ngRepeat:dupes] Upon searching documentation I found that AngularJS allows duplicate values by syntax "Track by $index" and example is shown to repeat single dimension json. My question is, how can I control my repeater with id

jQuery Please note that if I remove $scope.$apply(), no error shows up but data is also not shown.
$scope.OpenTemp = function () {
var vFileName = $("#TempList").val();
$scope.sysmsg = 'Opening voucher from temporary location';
var to = "../../WHS/OpenTempJV.ashx";
var options = {
type: "POST",
url: to,
data: { vFile: vFileName },
error: function () {
ShowErrorMsg("Error in opening temporary voucher");
},
success: function (data) {
if (data != "") {
//alert(data.d);
//$scope.sysmsg = 'success';
$("#divGrid").show();
$scope.TDS = $scope.TDS.concat(data);
//$scope.TDS = data;
//$scope.$apply();
//CalcAllTotals(data);
}
else {
ShowErrorMsg("Could not retrieve temporary voucher");
}
}
};
$.ajax(options);
}
