Nested object not saved on create - ruby-on-rails

Question

I am trying to make a new Deliverable which has nested DeliverableDates. The Deliverable's attributes, such as title, save but the nested attributes in DeliverableDates don't. What am I missing?
Many Thanks
class ProgramManager::DeliverablesController < ProgramManager::ApplicationController
...
def new
#deliverable = #program.deliverables.build
#program.groups.each do |group|
#deliverable.deliverable_dates.build(group_id: group.id)
end
clean_deliverables
3.times { #deliverable.select_options.build }
end
def create
delete_empty_select_options
#deliverable = #program.deliverables.new(params[:deliverable])
clean_deliverables
if #deliverable.save
redirect_to program_deliverables_path(#program), success: 'Deliverable created successfully'
else
#program.groups.each do |group|
#deliverable.deliverable_dates.build(group_id: group.id)
end
render :new
end
end
...
end

In order to make the 'accepts_nested_attributes_for' work properly ":deliverable_dates_attributes" must be added to the attr_accessible for the Deliverable
