[jQuery] double ajax calls don't work in IE

[jQuery] double ajax calls don't work in IE


hi
got this problem:|
i load a page in a div with the load method using this function:
$("#myLink").click(function(){
        $("#myDiv").load("myPage.php", function(){
                    myFunction();
                    });
        return false;
    });
myPage.php has a dropdown menu which makes another load in a div
var myFunction= function() {
        ("#myDropdown").change(function() {
        gruppo = $("#myDropdown").val();
        $("#myDiv2").load("myPage2.php.php?id="+id, function() {
                             myFunction2();
                             });
        });
    }
it works fine in firefox but not in ie which doesn't show anything
after i choose something from the edrop down.
i guess is something related to linking the function at the right
moment but i'm not really good in Javascript.
Any suggestion?
thanks vitto
