commonModalDialogClose not firing on chrome

Question

I have the next script on my page
Parent

function triggerModal(b,a)
{
    // if the url contains mysite - open it in showModalDialog 
    if (a.toLowerCase().search("person.aspx")>0 || a.toLowerCase().search("organizationview.aspx")>0)
    {
        ExecuteOrDelayUntilScriptLoaded(function () {
            var options = {
                url: a,
                tite: 'Mi Ficha',
                autoSize: true,
                allowMaximize: false,
                showClose: true,
                dialogReturnValueCallback: myDialogCallback
            };
            SP.UI.ModalDialog.showModalDialog(options);
        }, 'sp.js');
    }else{
        a:;STSNavigate(a)
    }
}
//THIS IS EXECUTED ONLY WHEN I CLOSE THE MODAL, NEVER WHEN I SEND THE OK
function myDialogCallback(target, strReturnValue) 
{
    if (target == SP.UI.DialogResult.OK) // Perform action on Ok.
    {
        triggerModal(null, "http://"+strReturnValue);
    }
}

Child

$(function() {
    $("div.s4-sn div.menu-horizontal ul li a").click(function(event) {
        SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.OK, "www.google.cl");
        return;
    });
});

This works perfectly on IE, but doesnt not work on Chrome. The script execute on Chrome but does not trigger the commonModalDialogClose.

Can somebody tell my what I'm doing wrong?
