I am trying to autocomplete in a input, It is working fine in Chrome,Safari&Firefox . It is not working on IE 9 alone. Please help.

    $("#name").autocomplete({
    select: function(event, iu) {
            id = event.toElement.innerText.split('-')       
            $("#id_estudiante").val(id[1]);
            $("#FinancieroGrid").load('php/Financiero/librerias/FindStudent.php?action='+id[1].replace(' ',''));                
          },
    source:'php/Financiero/function/getstuden.php',
    minLength:1
});
