hidden Fields not triggering the workflow

Hello All,

I have real time workflow in my  CRM 2013 , when a hiddenfield is updated using Javascript , worlflow is based on onchange of hiddenfield.

I can see the value changed on hidden field when it is in unhide mode but it is not even displayed in audit history.

Xrm.Page.getAttribute('hiddenIshandled').setValue('Yes');
Xrm.Page.getAttribute('hiddenIshandled').setSubmitMode('always');
Xrm.Page.data.entity.save();
Xrm.Page.data.refresh(true);
