Hi Vik,
In the jgrid "+" settings, if you select "Checkbox" it will display a checkbox. If you select "Checkbox toggle" it will toggle the selection of the checkbox. BUT this has no processing until you link it to a button. See these examples:
- http://demo.seblod.com/seblod-plugins/joomla-pack
- http://demo.seblod.com/seblod-addons/exporter/joomla-articles
See it displays a checkbox (which you would usually apply to the ID field) and in the exporter example it has some functionality.
What it is NOT (and where I think you are confused) is a "toggle status" button
The Status Toggle feature that you are looking for will be an upcoming addition to SEBLOD
