Force update in IndexedDB

I'm trying to forcefully update a database in IndexedDB by sending an open request with the current database's version number incremented by one with

var openRequest = indexedDB.open("db-name", dbVariable.version + 1);

however the onupgradeneeded event is never triggered and the openRequest stays in the pending state indefinitely.

What am I doing wrong?

Is there another way to forcefully update a database in IndexedDB?
