Rendering a javascript script error

I a using a jQueryUI dialog box which renders very well html code

search.html.haml =====

  • content_for :main_content do
    #content
    = form_tag query_plan_day_meals_path(:plan_id => @plan, :day_id =>
    @day), :remote => true do
    #error_messages{:style => “display: none;”}
    … form fields

I am now trying to render a javascript block given by our partner

search.html.haml =====

  • content_for :main_content do
    #content{:style => “width:300px;”}
    = render :partial => “myscript”

_myscript.html.erb

the dialog form is open correctly, but the script is not rendered in
it … ( #content div is empty)
and no error message … no request to this url…

why I am wrong ?
thanks for your feedback
