I'm a newbie in this, I'm trying to refresh a menu value (cart content) without reloading the whole page.

This is my issue : ${cartSession.getCartContent()} value in the alert check is Undefinied.

If it could help, In server side I'm using Spring.

$(document).ready(function(){

           var $form = $(#panierform);

           $form.submit(function(){

              $.post($(this).attr('action'), $(this).serialize(), function(response){



              },'json');

              alert(Ajouté avec succès !);

              refreshCartValue();

              return false;

           });



        });



        function refreshCartValue() {

            alert(${cartSession.getCartContent()});

            $(#cartValue).text();

            $(#cartValue).text(${cartSession.getCartContent()});

        }
