Sorting value fetched by jquery ajax call into javascript multidimensional array

I'd like to store a value that is correctly fe开发者_运维技巧tched via (NON ASYNC) ajax call (from facebook graph api) back to my javascript multidimensional array.

Everything works fine until the part when the data that I get from facebook api has to be stored to my previously defined 2d-array (and afterwards printed on the page via jquery append). I simply can't figure out where's the problem.

Here's the code sample:

Defining 2d array and its values:

fbpages = new Array (13);
i=0;
for (i=0;i<=12;i++) fbpages[i]=new Array(4);

fbpages[0][0] = "http://graph.facebook.com/120830347930692?callback=?"; 
fbpages[0][1] = "Kupi";
fbpages[0][2] = "/vijesti/tag/kupi/";
fbpages[0][3] = 0;

fbpages[1][0] = "http://graph.facebook.com/214014840762?callback=?";
fbpages[1][1] = "Kolek";
fbpages[1][2] = "/vijesti/tag/kolek/";
fbpages[1][3] = 0;

etc...

Fetch the data for every page using the URL from the array fbpages[x][0] and store it back to the same array, to the field fbpages[x][3]:

y=0;
for (y=0;y<=12;y++){
    pageURL = fbpages[y][0];
    fetchData(y,pageURL);
};

function fetchData (index,fbpageurl) {
        $.ajax({
            type: "GET",
            url: fbpageurl,
            dataType: "json",
            async: false,
            success:function(data){fbpages[index][3]=data.likes;}
        });
};

Data printing works fine.

Thanks in advance!
