How to update table contents using generator.yml?

Question

I use Symfony 1.3 at work. Displaying lists using admin generator and modifying generator.yml but I cannot update the lists. （id asc → desc etc..）

I tried cache clear command as below.

php symfony cc

I expect to update the table when modifying generator.yml. If I try in the wrong way, I'd like to know how to update the table in the right way.
