Better can be used as a verb, see https://www.macmillandictionary.com/dictionary/british/better_4
However it is quite unusual to use it in the sense of improvement (as here) rather than to outdo something, there are just a few almost idiomatic circumstances where it is used: "to better oneself/yourself", "to better relations"
The suggested usage may not be technically incorrect, but it is so unusual that it immediately identifies a non-native speaker
