Answer 1

We use the Jenkins Bitbucket Webhook and it works well.
It's for Bitbucket Server 4.0.0 - 4.14.4

I hope this helps.

EDIT: Today (Nov, 2017), this add on is not free, but worth the cost.

Answer 2

Under Build triggers there is a checkbox with label "Build when a change is pushed to BitBucket" check this box, when changes are pushed to bitbucket it will start a build.
