Had to solve the same problem, I used a member_action to solved it. Here's my solution:

member_action :remove_member, method: :post do
   user = User.find(params[:user_id])
   resource.users.delete(user)
   redirect_to resource_path, notice: I18n.t('admin.clubs.remove_member_success')
end

In show section:

panel do
  table_for club.users do
     column :rut
     column :last_name
     column do |user|
       link_to(I18n.t('admin.clubs.remove_member'),
         remove_member_admin_club_path(resource, user_id: user.id),
         method: :post,
         data: { confirm: 'Are you sure?' })
       end
   end
end
