ah shoot, submit can also be triggered pressing "enter"...
guess we're stuck with this then...... opinions ? (if everybody agrees I'll 
send a PR)

trap_form: function (action, target) {
      /* traps any LOADed form */
      $('#' + target + ' form').each(function (i) {
        var form = $(this);
        form.attr('data-w2p_target', target);
        if(!form.hasClass('no_trap')) {
          form.submit(function (e) {
            console.log(form.serialize())
            web2py.disableElement(form.find(web2py.formInputClickSelector));
            web2py.hide_flash();
            web2py.ajax_page('post', action, form.serialize(), target, form
);
            e.preventDefault();
          });
          /* simulating behaviour of non-ajax forms, where the click on a 
submit
          button also submits its name and value */
          form.on('click', web2py.formInputClickSelector, function (e) {
            e.preventDefault();
            var input_name = $(this).attr('name');
            if (input_name != undefined) {
              $('<input type="hidden" />').attr('name', input_name)
              .attr('value', $(this).val()).appendTo(form)
            }
            form.trigger('submit');
          })
        }
      });
    },
