How to update the internal status of workflow to completed after workflow temination in document library using JSOM.

I have terminated workflow in document library using JSOM code as below:

workflowInstanceService.terminateWorkflow(instance);

It is terminating workflow properly but not updating the internal status of workflow. It is still showing internal status as In Progress. See Below.

Internal Status:

Terminated

Status:

In Progress

I want to update internal status as Completed using JSOM.
