The best way to get anyone to read your fiction is to label it, "R&R, please!" and nothing else. It lets people know what your priorities really are, so they won't waste their time reviewing those people who only care about writing good stories.
And the best thing to do when readers did not rate and review after reading your fanfiction is express your feelings, you made a very awesome fanfic with "awesome-ly" perfect characters and they won't bother to "R&R"? How hurtful!
Tell them you've become uninspired because of them not commenting on your fic. When you make another chapter make sure to put a "R&R" quota, 10 "R&Rs" maybe? And warn them that you won't write the next chapter when your fanfic did not receive the minimum R&Rs it deserves.
