I'm working with rails 3.1.0 and this is my first application on 3.1.0
I have a remote link: 
link_to "my link",{:controller=>"my_controller",:action=>"my_action"},:remote=>true
and in my_controller I have 
def my_action
    @data = Data.all
    render :update do |page|
        page.replace_html "show_data",:partial=>"data_partial"
    end
end
but then in the log I get an error
ActionView::MissingTemplate (Missing template my_controller/update...
and I was checking at this post

do I really need to use a coffee script or a js.jrs to do this thing ??
