I inherited a model and put in a method for a scheduled action with some helper functions. I'm getting this error when i run it from the front end why?

NameError: name 'do_something_else' is not defined

I have something like this..

classProducTemplate(models.Model):    
	​_inherit = 'product.template'​

	​def action_do_something(self):
	​	​do_something_else()
	​@staticmethod
	​def do_something_else():
	​	​pass
