jQuery datatables is coded to use the success callback in ajax and it breaks if you intercept it. Source

You can also make use of jQuery ajax dataFilter callback .

$('table[id=entries]').DataTable({
    processing: true,
    serverSide: true,
    ajax: {
        type: 'POST',
        url: 'http://example.com/entries',
        dataFilter: function(response) {
            var json_response = JSON.parse(response);
            if (json_response.recordsTotal) {
                alert("There're entries");
            }else{
                alert("There're no entries");
            }
            return response;
        },
        error: function (xhr) {
            console.error(xhr.responseJSON);
        }
    }
});

Note: Return a String , not JSON in dataFilter callback.
