hook_condition_execute_CONDITION defined in ffc.api.php doesn't get called.

I implemented this hook, together with the hook_ffc_conditions_info, etc.. in a custom module, but i noticed that my hook didn't get executed.
The problem is the following:

on line #97 of ffc.module, the fuction name is the following :

$callback = 'ffc_condition_execute_' . $condition['condition'];
if (function_exists($callback)) {
        $callback($build, $field_name, !empty($condition['configuration']) ? $condition['configuration'] : '', $context);
      }

and that's the only function which gets called, no module hooks get called as well.

Imo, there are two solutions: change the hook name to ffc_condition_execute_CONDITION like you did with ffc_condition_form_CONDITION
or make the hook work ;)
