Add additional existing records to a nested form using AJAX and Rails 4

Question

I'm writing a form with nested attributes in Rails 4. I need to add an existing record to a list within a nested form, but I don't know how to preserve the f builder from the parent form, after the ajax call. Is there a way to write this into the session?

Please, for clarity, I am not adding a new empty record, but an existing record, which the user can proceed to modify.

Adding this to the controller works.

@f = ActionView::Helpers::FormBuilder.new(:object, @customer, view_context, {})

And then in the js.erb file

$("some-div").html("<%= j render('some_partial', f: @f) %>");
