Rails unobtrusive javascript (UJS) ajax:before append data params

I'm trying to append some parameters to a form before sending via ajax (via Rails UJS).

  $(document).on("ajax:before",".form-example", function(event) {
    event.data = $(":hidden").serialize();
  });

The hidden inputs aren't within the form, so I need to collect them, serialize the, and add them to the request (which is a PUT request). However, in the above example, no parameters are being passed to the server, am I doing something wrong? How can I pass parameter called "items" with the serialized values of hidden inputs?

Looking into this, it is actually possible to do, but you do not use the event, you modify the form itself (using $(this)).

So something like this could work:

$(document).on("ajax:before",".form-example", function() {
  var form = $(this);
  form.append($('<input />',{name: 'hidden_values',value: $(":hidden").serialize()}));
});

And you should be able to access the data in your rails action using params[:hidden_values].
