Vote-caster updates the votes count poorly

About

Vote-caster updates the votes count to 1 or -1, when the post is voted up or down, respectively. Two things to note, which may be helpful in finding the reason:

• This is purely visual, and the counter shows the proper value after a page refresh.
• This only happens if the user is voting that post for the first time. For this reason, it can be seen only if the user votes a post that has already been voted, and has non-zero votes.
