jQueryUI selectmenu refresh bug

jQueryUI selectmenu refresh bug

Hi all ,

Found a bug in the selectmenu button event handler management.  It is almost unnoiticeable, but  causes  unneded  memory/cpu consumption ,  i.e  slow downs etc .. 

Basically , if I initialize a  selectmenu ,   an appropriate  button is created  automatically with some event handlers attached to it .

That is fine , but if I call  selectmenu("refresh")  multiple times then  -  I see the number of remove() event handlers attached to the button increases.  Each time I call refresh the button gets extra remove()  event handlers - looks like the number of extra handlers ==  the number of menu options ...
