Rails - Feb 2006 - Link_to_remote with dynamic textbox

I''m trying to build a custom spell-checker. When an incorrect word is 
found, a select list is populated with suggestions, and when a 
suggestion is clicked, a "replacement_text" textbox is populated with 
the value. I''d like to be able to use a link_to_remote item to update 
the item. However, I can''t figure out how to pass the parameter to my 
"replace" action in my controller. I''ve tried:

    link_to_remote(
        suggest_item,
        :update => "id__#{word_count}",
        :url => {
            :action => ''replace'',
            :id => word_count,
            :with =>
"$(''replacement_text'').value"
        }
 


but the literal "$(''replacement_text'').value" gets
submitted rather than
the actual value of the "replacement_text" box.
