Ok, i had a few problems because i was inside a
$('.my-dropdown').live('click', function()
);
I had multiples inside my page that's why i used a class.
My drop down was filled automatically by a ajax request when i clicked it, so i only had the element $(this)
so...
I had to do:
$('.my-dropdown').live('click', function()
total_tems = $(this).find('option').length;
