ngTable.reload() unable to refresh ng-table does not show new data second time

Question

ngTable.reload() unable to refresh ng-table does not show new data second time code for index.js where i'm binding ng-table data.

First time databinding working properly. second time data is not binding properly. it shows previous data. so basiccally it is unable to bind data and unable to refresh

 $http.get("GetValidationsDataForTable", { params: { "entity": entity } })
                 .success(function (response) {
                     $scope.tableValue = response;
                     $scope.tableParams = [];
                     $scope.tableParams = new ngTableParams(
                         {
                             page: 1,            // show first page
                             count: 5          // count per page
                         },
                         {
                             groupBy: 'Entity',
                             total: $scope.tableValue.length,
                             getData: function ($defer, params) {

                                 var orderedData = params.filter() ?
                            $filter('filter')($scope.tableValue,    params.filter()) :
                            $scope.tableValue;

                                 var orderedData = params.sorting() ?
                                         $filter('orderBy')($scope.tableValue, $scope.tableParams.orderBy()) : scope.tableValue;

                                 orderedData = params.filter ?
                            $filter('filter')(orderedData, params.filter()) :
                            orderedData;
                                 params.total(orderedData.length);
                                 $defer.resolve($scope.tableValue.slice((params.page() - 1) * params.count(), params.page() * params.count()));
                             }
                         });
                     $scope.tableParams.reload();
                 })

code for index.cshtml

  <table id="tblValue" ng-table="tableParams" class="customTable" style="table-layout:fixed;max-width:100%">
                    <tbody ng-repeat="group in $groups">


                        <tr ng-hide="group.$hideRows" ng-repeat="validation in group.data" style="table-layout:fixed;">

                            <td data-title="'Property'" style="width:10%;text-align:left !important;overflow:hidden;">
                                <label id="lblProperty" ng-model="validation.Property" for="Property" ng-hide="editmode" style="width:97%;word-wrap:break-word; overflow-wrap:break-word;">{{validation.Property}}</label>

                                <select class="form-control" data-ng-model="validation.PropertyChoice" data-ng-options="choice.Name for choice in CurrentEntityProperties" ng-change="ChangeValidationRules(validation)" ng-show="editmode" style="width:100%; ">
                                    <option value="" style="margin-left:25px">-Select Property-</option>
                                </select>

                            </td>
                        </tr>
                    </tbody>
                </table>

why ngtable.reload() does not work and also not showing new data second time?

Solution is :

$scope.tableParams = {};
    $http.get("GetValidationsDataForTable", { params: { "entity": entity } })
                 .success(function (response) {
                     $scope.tableValue = response;
                     $scope.tableParams = [];
                     $scope.tableParams = new ngTableParams(
                         {
                             page: 1,            // show first page
                             count: 5          // count per page
                         },
                         {
                             groupBy: 'Entity',
                             total: $scope.tableValue.length,
                             getData: function ($defer, params) {

                                 var orderedData = params.filter() ?
                            $filter('filter')($scope.tableValue,    params.filter()) :
                            $scope.tableValue;

                                 var orderedData = params.sorting() ?
                                         $filter('orderBy')($scope.tableValue, $scope.tableParams.orderBy()) : scope.tableValue;

                                 orderedData = params.filter ?
                            $filter('filter')(orderedData, params.filter()) :
                            orderedData;
                                 params.total(orderedData.length);
                                 $defer.resolve($scope.tableValue.slice((params.page() - 1) * params.count(), params.page() * params.count()));
                             }
                         });
                     $scope.tableParams.reload();
                 })

i.e before every request make table parameters blank.
