OK, I googled "requirejs cache bust" for you and found this existing SO answer, which says you can configure requireJS with an urlArgs parameter, which is only a partial solution, but it might be enough to meet your immediate needs.

That said, the cachebusting problem is full of challenges and many "solutions" don't actually solve the problem in its entirety. The only maintainable way to do this (IMHO as of now) is with a full-on asset management system like the Ruby on Rails asset pipeline or connect-assets or the equivalent for your server side framework of choice. Those can correct compute a checksum (usually MD5 or SHA1) of the content of each file and give you the file names you need to put as URLs in your HTML script tags. So, don't bother with manually changing filenames based on version numbers, just use checksums since they are easily automated and foolproof.

From what I can tell, out of the box requirejs can't do the cachebusting aspect for you. You might want to read this google groups thread. Otherwise, you may need to pair requirejs with an additional tool/script to get you good cachebuster checksums.
