[jQuery] loader for ajax/load

[jQuery] loader for ajax/load


hi
i want to show/hide a loader when using load() function. With this
script:
$('#load')
    .ajaxStart(function() { $(this).show(); })
    .ajaxStop(function() { $(this).hide(); });
$('#colCont').load('myFile.php?id=myId #colContIns');
$('#categorie a').click(function(){
                    $('#categorie a').removeClass('selected');
                    $(this).addClass('selected');
                    var id = $(this).attr('id');
                    var s = new Array();
                    s = id.split('_');
                    $('#colCont').load('prodotti/famiglie.php?id='+s[1]+'
#colContIns');
                    return false;
});
the loader shows only on its first call but not when i load html
fragments from links.
Any idea why?
Thanks Vitto
