How to delete a job?

[dasegos]

Hello, I have a question on your library!
I need to abort a job once it is clicked on a button. I create a Job object with job’s ID and then abort it. However, it’s executed and only then it is deleted. What’s more, the «exit code» is False, which means, according to your documentation, improper deletion of a job.
What can be wrong? How to delete a job properly?
