jquery - click event for option doesn't work in IE

Question

I have a multiple select tag, and I need to write the function onclick of it's options, because I need to get the value of last clicked option, but when I wrote the following

$("#multiple_select option").click(function()
{
     var val = $(this).val();
     alert(val);
});

it doesn't work in IE.

What is the problem?

UPDATE

I need exactly click event, because I wrote a function onclick event already(demo here), and I need to fix last changed element's value, which is impossible to make without click event(I think)

Answer 1

don't bind it on option

$("#multiple_select").click(function(){
     alert("works");
});

accepted answer:

$(document).ready(function()
{
    var options = $("#supply_cities_select :selected");
    var lastOption;
    $("#supply_cities_select").click(function()
        {
            lastOption = $(this).find(':selected').not(options);
            options = $(this).find(':selected');
        })
});
