    <umb-table ng-if="versions"
               items="versions"
               item-properties="myColumnProperties">

</div>
angular.module("umbraco").controller("DamVersionsController", function ($scope, $http, $routeParams) {
    $scope.versions = [];
    $scope.currentMediaId = $routeParams.id;

    $scope.loadVersions = function (mediaId) {
        $http.get("/umbraco/surface/damversions/getversions", { params: { mediaId: mediaId } })
            .then(function (response) {
                if (response.data && response.data.length > 0) {
                    $scope.versions = response.data;
                } else {
                    console.log('No versions data received');
                }
            }, function (error) {
                console.error('Error fetching versions:', error);
            });
    };

    $scope.myColumnProperties = [
    {
        alias: "name",
        header: "Name",
        allowSorting: true,
        isSortColumn: true,
        sortDirection: "asc"
    },
    {
        alias: "date",
        header: "Date",
        template: "<span>{{item.date | date:'yyyy-MM-dd HH:mm:ss'}}</span>",
        cellClass: "text-center"
    },
    {
        alias: "isActive",
        header: "State",
        template: "<span>{{item.isActive ? 'active' : 'noactive'}}</span>",
        headerClass: "text-bold"
    },
    {
        alias: "actions",
        header: "option",
        template: "<button class='btn btn-danger' ng-click='deleteItem(item)'>delete</button>
<button class='btn btn-danger' ng-click='modifyItem(item)'>modify</button>"
