It appears that the method to handle the params() is never called. Maybe I have
to write some javascript to call this method onLoad and OnChange?
Is there a way of doing this in Rails?
The select is part of a larger page - there is no "submit" button
The other issue is how to get the current provider selection to the select list
- there is a way to do this in options_for_select but I cant for the life of me
get it to work
