I have a partial view which incorporates on onChange option in a form.  
It works great when I actually change the select box which it is an  
option to. However, when the div which contains this partial first  
shows, the onChange doesn;t fire. How can I force this to fire when it  
is first shown? Thanks Janna B,

\<%= f.label :country %\>  
  
\<%= f.country\_select :country, Carmen.default\_country, {},  
{  
:onChange =\> remote\_function( :url =\> { :action =\>  
‘\_get\_states’ }, :update =\> “state”, :with =\> “‘country=’ +value”)  
} %\>
