Just a correction in order to rewrite the ID as well:

          
var $new_obj = $('<fieldset></fieldset>').html($content_item.find('fieldset:first').html()
  .replace(new RegExp(name + '_0', "g"), name + '_' + number).replace(/\[0\]/g, '\[' + number + '\]'));

I use a different approach:

          
        
// application.js
$('form').on('click', '.add-fields', function(e) {
    var $content_item = $(this).closest('.content-item');
    var number = $content_item.find('fieldset').length;
    var name = $(this).data('name');
    var $new_obj = $('<fieldset></fieldset>').html($content_item.find('fieldset:first').html().replace(/\[0\]/g, '\[' + number + '\]'));
    $(this).before($new_obj);
    $new_obj.find(':input').not(':hidden, :checkbox, :radio').val('');
    $new_obj.find(':checkbox, :radio').prop('checked', false);
    e.preventDefault();
});

# _form.html.erb
<%= link_to 'Add', '#', class: "add-fields", data: {name: :person_cars_attributes} %>

This way I don't need any helper_method.
