If
value="{{student:s['First Name'], status: absent}}"
Is exactly what you hard coded on your iteration, the note that’s the reason why all your checkbox are checked on a click.
The values of the checkbox should be unique.
To pass dynamic values to ur input, you should bind them.
E.g
:value="object"
// Where object is a valid know JavaScript object
Binding let’s you pass dynamic value to your template.
