jQuery Grid Plugin - jqGrid

Through server-side code, I'm creating a checkbox column through a CustomFormatter.

My client side function returns the following syntax : <input type="checkbox" name="checkbox123" />.

I have a button which fires a client-side function in which I want to check which items were checked by the user.

When declaring an instance of my grid through jquery, I can see my columns, however, the checkbox column does not have an ID.

Therefore, I'm unable to reference it. I need to be able to check the checked state of the checkbox column I've created.

How can i accomplish this?

Thanks
