How to create a new objectStore in Indexeddb without reloading the page?

Question

JavaScript

There is an indexeddb base already with several objectStore. It is necessary without deleting the base and without recreating to add one or two more objectStore. Per the documentation, createObjectStore and deleteObjectStore are only called in the versionchange event. I can't find an example of how to call versionchange without reloading the page. Please help.
