Filter with text field and checkbox

Hi everyone,
So, site is getting there slowly.

I have a list of users, and want to filter that by name and active status.
Filtering by name via text field is fine, works brilliantly.
However, I also want to be able to filter via clicking the checkbox.
So basically via either the searchable text box and then either with checkbox to show active and inactive users.

I have in my table a field called active, and can update this no problem, giving 1 or empty field. What I can’t seem to do is get the checkbox to work and filter.
Ive looked at the how-to with multiple checkboxes etc.
When i bind the value of my checkbox to a text field, its giving true or false, is this the issue as i need it to filter on 1 or empty in my table?

Any suggestions ( assuming above makes sense).
