Is there any way to update attributes for miltiple objects with nested form?

I used this code in controller:

@works = Work.find(params[:work_ids])
@works.reject! do |work|
   work.update_attributes!(params[:work])
end

if @works.empty?
   redirect_to contracts_path
else
   render :edit_multiple
end

It is similar to example

But instead of updating the records, Ruby creates new ones and nullifies "work_id" in existing records.

mysql> SELECT * FROM work_comments;
+----+---------+-------------+
| id | work_id | content |
+----+---------+-------------+
| 1 | NULL | comment |
| 2 | NULL | comment |
| 3 | NULL | comment |
| 4 | 1 | new comment |
| 5 | 2 | new comment |
| 6 | 3 | new comment |
+----+---------+-------------+
6 rows in set (0.00 sec)

What could cause this problem? Thank you!
