There is a problem in using template fragment caching, that is, we need
transfer `data` for template every time, even the data has been in cache.
If the data acquisition process is time consuming (such as 3 seconds),
template caching has no helpful.
My idea is to allow provide a callback function to tell the cache how to
get the data. and only call the function when cache expires.
I have tried it many times and found out how to make the simplest changes
to complete this feature and ensure its compatibility.
