Pass value from href jquery to Spring MVC

Good afternoon, I'm having trouble passing an id that is in the jquery href to the Spring MVC controller update method. Can anybody help me. Thank you.

$.ajax({
        url : "listAllForum",
        dataType : 'json',
        success : function(data) {
            $.each(data, function(index, objeto) {
                $('#post-forum').last().append('<div class="jumbotron"> <strong>Nome do usuário que postou a mensagem!!!</strong> - ' 
                        +' Data: <br>' + objeto.message + '<br> <br>'
                        + '<input type="text" size="90" placeholder="Redigir uma resposta" id="answer" name="answer" />'
                        + ' <br> <br> <a href='**/update/**' + objeto.idForum + '>Responder</a> </div>');
                });
        }
    });

When clicking on Reply, instead of calling the controller method, it calls an update page.
