examples doesn't work only on help page

hi,

from http://www.mydomain.com/admin/help/ajaxtable_docs with copy/paste i created new ajaxtable.
the ID is other:

function ajaxtable_table_ajaxtable_test1($override='') {
  ajaxtable_override($table,$override);
return $table;
}


print ajaxtable_render("ajaxtable_test1");

for start the table is populated with data, but when i want to search or sort i get no data.
in help page works the sort and search too.
any idea?
