Disable BeanFactory cache

I’m trying to fill ‘non-db’ ‘html’ type field in controller. To be more specific I’m building small table from the JSON string kept in ‘varchar’ field in the same record. Adding Jeditable plugin let me edit JSON values in-place. And updating record works OK but when I hit F5 to reload the page it still displays old value.
As far as I understood each time I reload the page controller takes in its $this->bean property cached copy of the bean. I tried a trick with $newBean = BeanFactory::getBean(‘ModuleName’)->retrieve($oldBean->id) but it still returns cached copy. Seems like Sugar 7 have options to avoid caching bean . But what about Suite? Any other ideas how to disable bean caching for particular module?
