I am using jQuery DataTables. After ajax request, I call the ajax.reload() method to refresh my dataTable but I lose the current page. It returns the first page.

Here is my DataTables init:

datatable_appointments = $('#datatable_appointments').DataTable({

    responsive : true,

    processing : true,

    serverSide: true,

    bSort : false,

    ajax: function(data, callback, settings) {

        // make a regular ajax request using data.start and data.length

        $.get(URL_API + URL_APPOINTMENTS_STATE + '/', {

            limit: data.length,

            offset: data.start,

            search: data.search.value

        }, function(res) {

            if (res.error) {

                callback({

                    recordsTotal: 0,

                    recordsFiltered: 0,

                    data : 

                });

            } else {

                data_appointments = res.data;

                // map your server's response to the DataTables format and pass it to

                // DataTables' callback

                callback({

                    recordsTotal: res.total_data,

                    recordsFiltered: res.total_data,

                    data: res.data

                });

                $(#datatable_appointments > tbody > tr > td).addClass(text-center);

                $(#datatable_appointments > tbody > tr > td).css(vertical-align, middle);

                $(#datatable_appointments > thead > tr > th).addClass(text-center);

            }

        });

    },

    columns : [

        { data: service_name},

        { data: doctor_info},

        { data: patient_name, render: function (data, type, row, meta) {

            return row.name +   + row.surname;

        }},

        { data: appointment_date, render: function (data, type, row, meta) {

            var formattedDate = new Date(row.appointment_date);

            var day = formattedDate.getDate();

            var month =  formattedDate.getMonth();

            var hours = (formattedDate.getHours().toString().length == 1) ? '0' + formattedDate.getHours() : formattedDate.getHours();

            hours += ':';

            hours += (formattedDate.getMinutes().toString().length == 1) ? formattedDate.getMinutes() + '0' : formattedDate.getMinutes();

            return day + ' ' + months[month] + ', ' + hours;

        }},

        { data: state, render: function (data, type, row, meta) {

            if (row.state == '0')

                return '<i class=fa fa-circle font-red-mint></i><br />İptal';

            else if (row.state == '1')

                return '<i class=fa fa-circle font-green-jungle></i><br />Onaylı';

            else if (row.state == '2')

                return '<i class=fa fa-circle font-grey-salsa></i><br />Beklemede';

        }},

        { data: actions, render: function (data, type, row, meta) {

            if (row.state == '2')

                return '<div class=btn-group btn-group-circle>' +

                            '<button type=button onclick=setState(''+row.id+'', '1'); class=btn btn-outline green btn-sm>Onayla</button>' +

                            '<button type=button onclick=setState(''+row.id+'', '0'); class=btn btn-outline red btn-sm>İptal Et</button>' +

                        '</div>';

            else

                return '';

        }}

    ],

    sPaginationType: full_numbers,

    language: {

        emptyTable: Kayıt bulunamadı.,

        sZeroRecords: Bu kriterde sonuç bulunamadı.,

        search: Bul,

        sProcessing : <img src='/assets/global/img/loading-spinner-blue.gif' />,

        sInfo: Toplam <b>_TOTAL_</b> veri bulunmaktadır.,

        sLengthMenu: Gösterilen kayıt sayısı _MENU_,

        sInfoFiltered: ,

        sInfoEmpty:,

        paginate: {

            sPrevious: Önceki,

            sNext: Sonraki,

            sFirst : İlk,

            sLast : Son

        }



    }

});

And my setState method in same js file:

function setState(id, state) {

    $.ajax({

        url : URL_API + URL_APPOINTMENTS_STATE + '/' + id,

        type : 'put',

        data : {'state' : state},

        dataType : 'json',

        success : function (response) {

            if (response.error) {



            } else {

                datatable_appointments.ajax.reload();

            }

        }

    });

}
