How to let user set find_by conditions for Sortable and Editable Datagrid sample?

"Sortable and Editable Datagrid for Ruby on Rails" is very useful and easy to use.

I developed a nice page by using this sample.
I need help to work something out:

Instead of load whole table with @users=User.all(), I need add a "text_field_tag" like
Ajax to passing a params from view to controller. So I can change @users=User.all() to

term = parama[:name]
 @users=User.all(:conditions => ["name LIKE ?", "#{term}" + "%"])

I intend to use for_remote_tag and text_field_tag. It return the right data but all in one string. Also it can not fit into original grid table as expected.


Thanks
