jquery parsejson not working

In a different post named "confused how to use jquery getJSON properly" I was having difficulty on how to make my ajax call work and peoples' comments helped me out. But my jquery ajax call still isn't working:

$(document).ready(function(){   
    $("input#autofill").click(function()
    {
        $.get("last_year_ISBN.php",
                  function(data){
                  alert(data);
                  var isbns = $.parseJSON(data);    //creates a javascript object.
                  var elements = $('#booklist .ISBN_number');
                  $.each(isbns, function(index, obj){
                    alert("hello");
                    $(elements[index]).val(obj);
                    });
                  },
                  "json");



    });
});

The first alert(data) properly prints out the json, so I know the ajax call works. but when I did a debug with firebug, I found out that the variable isbns is set to null. Also, when I put an additional alert("hello") inside the callback function it wasn't called and didn't appear on the screen. Can someone help me figure this out?

Try using $.getJSON() This will automatically treats your response as JSON.

Try running the alerted "json" through a validator like jsonlint.com. If it's not valid json, it will fail to create the object.
