Term Aggregation - Custom order

[annelhote]

Hello,
Is there a way to create a custom function to order the buckets in my aggregation ?
Right now, my page has a div like that :
eui-aggregation="ejs.TermsAggregation('sites').field('sites').size(sites.size)"

I would like to be able to write a JS function to re-order my buckets.

Any help appreciated ! :)
