How to remove branch from list of branches?

[gleb-svechnikov]

I need to manage list of branches listed by this code.

app.get('/branches', function (req, res) {
    repo.remote_fetch('origin', function (err) {
        console.log(err);
    });
    repo.remotes(function (err, remotes) {
        console.log(err);
        res.json(remotes);
    });

});

Currently it lists some of them, only that I requested explicitly with

git checkout branch-name

I've removed some of local branches with:

git branch -d needless-branch

But JSON that I see on localhost:3000/braches URL still contains needless-branch
I've tred to stop application and run it again - it did not help.
Can anybody suggest how to remove needless-branch from list of branches?
