Rails - Aug 2006 - how to update a collection_select from another

I have two collection_select in my list.rhtml:
<%= collection_select (:region, :id, @regionall, :id,
:title,html_options={:onChange => "new
Ajax.Updater(''related_provinces'',''/categories/related_provinces/"
+
"?id=''+this[this.selectedIndex].value,
    {asynchronous:true, evalScripts:true});"}) %><br>
<%= render :partial => "related_provinces" %>

This is my partial:
_related_provinces.rhtml:
<%= collection_select(:region, :id, @provinces, :id, :title) %>


category_controller.rb:
def list
 @regionall = Region.find(:all, :conditions => [ "parent_id = ?",
''1''],:order=>"id")
 @provinces = Region.find(:all, :conditions => [ "parent_id = ?",
@region.parent.id],:order=>"id")
end

The problem is that it doesn''t even display the onChange javascript
code:

 <select id="region_id" name="region[id]"><option
value="2">bla1</option>
<option value="3">bla2</option>
<option value="4">bla3</option></select><br>
<select id="region_id" name="region[id]">
<option value="61"
selected="selected">blop1</option>
<option value="62">blop2</option>
<option value="68">blop3</option></select>

Could you please tell me first why my JS code isn''t display and second
if the ajax update JS code is correct? :)

Thanx in adance
