[jQuery] Selct Field Change trigger, Multiple is fine .. single not run


Hy ..
I try to modify this example: http://docs.jquery.com/Selectors/selected
With multile select run ok if I use arrow key to modify the value
But the select is: <select name="garden" multiple="multiple">
...
I want single selected value and don't run when I press arrow
key .... :((
<select name="garden">
idea?
