Refresh DataTable after ajax call

OnLog

Hi, I have a right click function with ajax call to server. I would like the table to refresh after this call but I get "Invalid JSON".
Here is the function:

                //get right-click menu
                $(function () {
                    var MenuItems = [];
                    MenuItems = ContextMenuItems();
                    $('#dynamicTablePlain').contextMenu({
                        selector: 'tr',
                        trigger: 'right',
                        build: function ($trigger, e) {
                            var options = {
                                callback: function (key, options) {
                                    var column0 = new Array();
                                    var selectedRows = table.cells('.selected', 0).data();
                        
                                    for (var i = 0; i < selectedRows.length; i++) {
                                        column0.push(selectedRows[i]);
                                    }

                                    var items = MenuItems;
                                    var actionSP = items[key]._contextItemAction;
                                    var ResponseSuccessText = items[key]._responseSuccessText;
                                    var ResponseErrorText = items[key]._responseErrorText;

                                    $.ajax({
                                        contentType: 'application/json; charset=utf-8',
                                        dataType: 'json',
                                        type: 'POST',
                                        url: '/api/contextItemAction/post/' + actionSP,
                                        data: JSON.stringify(column0),
                                        success: function (response) {
                                            if (response.success) {
                                                alert(ResponseSuccessText);
--------------------------------------> here is where I would like to refresh <----------------------------------------------------------
                                            } else {
                                                alert(ResponseErrorText);
                                            }
                                        },
                                    })
                                },
                                // start with an empty map
                                items: {}                                
                            };
                            
                            $.each(MenuItems, function (k, v) {
                                options.items[k] = { name: v._contextItemName, icon: v._icon };
                            });
                            return options;
                        }                        
                    });
                });

What is the server returning if it isn't valid JSON?
