Afisare rezultate paginate la scroll page

Salut,
In baza de date am 23 de rezultate din care initial afisez doar 10 si as vrea ca atunci cand ajung cu scroll la finalul paginii sa imi afiseze inca 10 pana le afiseaza pe toate.Am facut scriptul asta doar ca afiseaza doar primele 10 si atat...unde gresesc?Multumesc!

Nu functioneaza findca ai definit functiile in ready().
Incearca scriptul js asa (daca nu functioneaza, verifica in consola browserului de eventuale erori js).

<script>
function getresult(url) {
  $.ajax({
    url: url,
    type: 'GET',
    data:  {rowcount:$("#rowcount").val()},
    beforeSend: function(){
      $('#loader-icon').show();
    },
    complete: function(){
      $('#loader-icon').hide();
    },
    success: function(data){
      $("#faq-result").append(data);
    },
    error: function(){} 	        
  });
}

$(window).scroll(function(){
  if ($(window).scrollTop() == $(document).height() - $(window).height()){
    if($(".pagenum:last").val() <= $(".total-page").val()) {
      var pagenum = parseInt($(".pagenum:last").val()) + 1;
      getresult('script_afisare.php?page='+pagenum);
    }
  }
});
</script>
In plus, in cod ai $("#rowcount").val(), dar in codul html nu ai un input cu id #rowcount, iar acea valoare o preiei si in php, dar lipseste in html.

Am rezolvat(era o litera gresit apasata pe acolo), imi merge scriptul, dar a mai aparut o eroare.
Eu am 21 de inregistrari in baza de date.
Daca pun $perPage = 2; imi afiseaza inregistrarea 1 si 2 iar cand ajung la capatul paginii imi afiseaza 3 si 4 iar apoi cand ajung iar la capatul paginii nu imi mai afiseaza nimic, scriptul se opreste acolo.
Aveti idee ce poate fi?
Multumesc!
