How to update the game using Browser plugin?

I'm curious how to update the game using Browser, there are two events are called "Is Downloading Update" and "On Updated", but i don't see an action "Download Update"

It's described in more detail in the offline games in Construct 2 tutorial. You simply reload the page to "install" the update.

I re-uploaded the updated .appcache and game data, then i reloaded the page... nothing happens, so i did it like 8 times.

Bump

You can't reload too quickly or the browser won't have finished downloading the update. Use Chrome and watch the console and it reports its progress. What does the Chrome console say?

Document was loaded from Application Cache with manifest xxxx.com/xxxx/offline.appcache

Application Cache Checking event

Application Cache Error event: Manifest fetch failed (401) xxxx.com/xxxx/offline.appcache

Ah, it seems an error

Check your server has the right MIME types set up as described in that tutorial.
