Django: BooleanField return 'on' instead of true? - django

Question

I have a BooleanField (ran_bug) in my Randomisation models that is displayed as a checkbox.
Click on the checkbox sould show 2 other fields that are not mandatory (ran_dem_nom and ran_dem_dat).
My problem is that, when I 'check' the checkbox, it return 'on' instead of true.
And I got an error when I try to registered data:
django.core.exceptions.ValidationError: ["'on' value must be either True, False, or None."]
