The data I added from the modal is successfully saved in the database. But I can't show it in the table. What's wrong with the code below? I'm new to ajax. tabbleadd() is defined as onclick on the button Thanks

onclick="Tabloyaekle()

''' function tableadd(data) {

$.ajax({
    type: "POST",
    url: '/Haberler/AddNews',
    data: data,
    success: function (data) {
        if (data.success) {

            var t = $('#exampleModalSizeLg').DataTable();
            t.row.add(data);
            Swal.fire(
                'Başarılı',
                'Eklendi',
                'success'
            )
        }
        else {
            Swal.fire(
                'HATA',
                '!' + data.mesaj,
                'error'
            )
        }
    },
    error: function () {
        Swal.fire(
            'HATA',
            'Eklenemedi',
            'error'
        )


    }
})
