Pagination controls not showing up in ng-table when fetching data from backend

Question

I am fetching a list of data from the backend and displaying it using ng-table. The problem is that its not showing the pagination controls. Previously, when I used dummy data to show the ng-table, pagination was working totally fine. Could someone help me out here?

This is my HTML:

<table ng-table="tableParams" show-filter="true" class="table">
            <thead>
                    <tr>
                            <th ng-repeat="column in columns" ng-show="column.visible"
                                    class="text-center" ng-class="{
                                    'sort-asc': tableParams.isSortBy(column.field, 'asc'),
                                    'sort-desc': tableParams.isSortBy(column.field, 'desc'),
                                    'sortable': !$first
                                    }"
                                    ng-click="tableParams.sorting(column.field, tableParams.isSortBy(column.field, 'asc') ? 'desc' : 'asc')">
                                    <div>{{column.title}}</div>
                            </th>
                    </tr>

            </thead>
            <tr ng-repeat="user in data | filter:searchText">

                    <td width="30" style="text-align: left">
                            <input type="checkbox" ng-model="checkboxes.items[user.id]" />
                    </td>

                    <td data-title="'Email Id'" class="text-center" sortable="email" ng-show="columns[1].visible">
                            <span>{{user.email}}</span>
                    </td>
                    <td data-title="'User Karma'" class="text-center" sortable="userkarma" ng-show="columns[2].visible">
                            <span>{{user.userkarma}}</span>
                    </td>
                    <td data-title="'Date Joined'" class="text-center" sortable="datejoined" ng-show="columns[3].visible">
                            <span>{{user.datejoined}}</span>
                    </td>
                    <td data-title="'Unsubscribed'" class="text-center" sortable="status" ng-show="columns[4].visible">
                            <span>{{user.unsubscribed}}</span>
                    </td>
            </tr>
        </table>

Below is my js file:

for (var i = 0; i < UserList.getUsers()
            .length; i++) {
            $scope.data.push({
                id: UserList.getUsers()[i]._id,
                email: UserList.getUsers()[i].email,
                userkarma: UserList.getUsers()[i].healthScore,
                datejoined: moment(UserList.getUsers()[i].firstSessionAt)
                    .format("MMMM Do YYYY"),
                unsubscribed: UserList.getUsers()[i].unsubscribed
            })
        };
        $scope.columns = [{
                title: '',
                field: 'checkbox',
                visible: true
            },
            {
                title: 'Email',
                field: 'email',
                visible: true
            }, {
                title: 'User Karma',
                field: 'userkarma',
                visible: true
            }, {
                title: 'Date Joined',
                field: 'datejoined',
                visible: true
            }, {
                title: 'Unsubscribed',
                field: 'unsubscribed',
                visible: true
            }
        ];

        $scope.tableParams = new ngTableParams({
            page: 1, 
                count: 10, // count per page
                filter: {
                    name: 'M' // initial filter
                },
                sorting: {
                    name: 'asc'
                }
            }, {
                total: $scope.data.length, // length of data
                getData: function ($defer, params) {
                    // use build-in angular filter
                    var filteredData = params.filter() ?
                        $filter('filter')($scope.data, params
                            .filter()) :
                        data;
                    var orderedData = params.sorting() ?
                        $filter('orderBy')($scope.data,
                            params.orderBy()) :
                        $scope.data;
                    params.total(orderedData.length); // set total for recalc paginationemail

                    $defer.resolve(orderedData.slice((
                            params.page() -
                            1) * params.count(),
                        params.page() *
                        params.count()));
                }
            });

This happens because the usual $scope.tableParams.reload() function used to refresh the data after an asynchronous data load does not refresh the total item count in the table. It didn't happen before because this value is correctly set at the beginning when you were using dummy data.

You need to add a params.total(data.length); the getData function to manually refresh the value.
