Link_to_remote with Modalbox.show

Rails
1

Hi
In helper I have
change_email_link
html = []
html << change_email_js(:email => @email)
html << %{
edit
}
html.join
end
Now
def change_email_js(options ={})
%{

}
end

   My problem is This does not popup the modalbox. But when I remove

the line
#{link_to_remote ‘Ok’,{},{:class => :new_ui_blue_button}} Or change
this link_to_remote to link_to everything works as expected What might
be the reason
Please help

Thanks in advance
Sijo
