[jQuery] Simple modal plugin - problem with setting focus in modal window

[Igor Benko]

Hi all,

I have this weird problem I just can't find a way to solve. I'm using
simpleModal plugin as login window and I want to set focus to username
input upon window showing, but can't manage to do that.
This is my code:
    $("#prijava_popup").modal(
    {opacity: 30,
        onOpen: function (dialog) {
            dialog.overlay.fadeIn(150, function () {
                dialog.container.slideDown(150, function () {
                        dialog.data.fadeIn(150);
                });
            });

            $('div#simplemodal-container input[name=uime]').focus();

        },
        onShow: function (dialog) {
            $('div#simplemodal-container input[name=uime]').focus();
           });

        }
    });

But it doesn't work, I can hide input field but can't set focus to it.
Is this solvable?

Thank you in advance for your answer, best regards, Igor Benko
