javascript - Rails; display modal after an action and page reload -

-

i have following code...

controller

... session[:registration_modal] = true redirect_to(event_path(@event))

_main.html.erb

... <!-- modal -->   <div class="modal fade" id="registration-modal" tabindex="-1" role="dialog" aria-labelledby="mymodallabel" aria-hidden="true">     <div class="modal-dialog">       <div class="modal-content">         <div class="modal-header">           <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>           <h4 class="modal-title">registration notice!</h4>         </div>         <div class="modal-body">           thank registering event. not receive $200 , not pass go!         </div>         <div class="modal-footer">           <button type="button" class="btn btn-default" data-dismiss="modal">close</button>         </div>       </div><!-- /.modal-content -->     </div><!-- /.modal-dialog -->   </div><!-- /.modal -->  <% if session[:registration_modal] == true %>   <%= render :partial => 'registration_modal'%>   <% session[:registration_modal] = false %> <% end %>

_registration_modal.html.erb

<script class="code" type="text/javascript">   $('#registration-modal').modal('show'); </script>

this code works. after controller action runs, modal popup. move modal code out of _main partial , _registration_modal partial. when that, modal broken. seems javascript looking #registration-modal in _main. how can tell in _registration_modal?

edit
