Here is my code:

```
$(".multiple").each(function() {
        $(this).bind("mousedown",function() {
            alert();
        });
    });

```

Here is the HTML it applies to:

```
<select>
<option value = "textbox">TextBox</option>
<option class = "multiple" value = "multiplechoice">MultipleChoice</option>
<option class = "multiple" value = "dropdown">DropDown</option>
</select>

```

I expect to see some sort of alert box, but it doesn't seem to function. How can I fix this?
