How to get dropdown selected id data in table grid in Angula

Question

<table >

<tr>

<th>Customer</th>

<th>Pendings</th>

<th>Pending Value</th>

</tr>

<tr ng-repeat="r in rvm">

<td>

<select ng-model="c" ng-change="GetAccountBalance($index,c)" ng-options="c.ID as c.Name for c in customer track by c.ID" style="width:150px;height:22px;" name="tCustomer">

<option value="">select Customer</option>

</select>

<input type="text" ng-model="ReceiptsViewModel.PendingAmount" class="input-large" name="tPendingValue" readonly />

</td>

<td>

<input type="text" ng-model="ReceiptsViewModel.AdjustAmount" class="input-large" name="tPendingAdjusted" readonly />

</td>

</tr>

</table>

JS

$scope.rvm = [{}];

$scope.GetAccountBalance = function (index, c) {

//adding new row on dropdown change

if ($scope.rvm.length == (index + 1)) {

$scope.rvm.push({

});

}

var getPendingData = ReceiptsService.GetPendings(c);

getPendingData.then(function (d) {

//var x;

//for (x in d.data)

//{

// alert('in');

// $scope.ReceiptsViewModel = d.data;

//}

alert($scope.rvm.length);

$scope.ReceiptsViewModel = d.data;

$scope.ReceiptsViewModel.PendingAmount = $scope.ReceiptsViewModel.Amount - $scope.ReceiptsViewModel.AmountAdjusted;

}, function (error) {

alert('Error');

});

}

controller

public JsonResult GetPendings(int? pendingID)

{

string eid = pendingID.ToString();

TestDemoEntities db = new TestDemoEntities();

var data = (from ap in db.Accounting_PendingBills

join apa in db.Accounting_PendingBillsAdjusted on ap.BillRef equals apa.TowardsBillRef

group apa by new { ap.BillDate, ap.Amount, ap.Party, apa.TowardsBillRef } into g

select new

{

BillDate = g.Key.BillDate,

Party = g.Key.Party,

Amount = g.Key.Amount,

BillNumber = g.Key.TowardsBillRef,

AmountAdjusted = g.Sum(aa => aa.AmountAdjusted)

}).Where(ap => ap.Party == eid).FirstOrDefault();

return Json(data, JsonRequestBehavior.AllowGet);

}

by using follwing table am adding new row on dropdown change,and getting selected id data from database ,and binding that to table,

my problem is same data is binding to that added new row also(except dropdown:it is showing select customer ).again if i select another

customer from database getting data correctly,but the data is binding to all.
