From http://prototypejs.org/api/element/fire :
Element#fire does not support firing native events. All custom event
names must be namespaced (using a colon). This is to avoid custom
event names conflicting with non-standard native DOM events such as
mousewheel and DOMMouseScroll.
What you want to to, is set the selectedIndex value from the <select>
element as is documented at http://www.w3schools.com/htmldom/dom_obj_select.asp
selectedIndex needs to be an integer. If you want to select it by
value, then you'll need to loop the values and when you find the right
one, check what index it has (selectedIndex is a getter and a setter)
and set it to that index.
