Odoo delegation inheritance delete corresponding records of inherited class

I've extended a default class using _inherits. I am using Odoo v9.

class new_product_uom(models.Model):  
_inherits = {'product.uom':'uomid', }  
_name = "newproduct.uom" 
uomid = fields.Many2one('product.uom',ondelete='cascade', required=True).
#declare variables and functions specific to new_product_uom
sellable = fields.Boolean('Sell products using this UoM?', default=True)
[...]

If I delete the corresponding record in product.uom, the new_product_uom is deleted.

If I were to delete a new_product_uom record, nothing happens to the corresponding product_uom record.

I'd like for BOTH records to be automatically deleted when either is deleted. Is there a way I can do this? Thanks in advance for the help.

Clarification:

product.uom is a default odoo class. It holds UoM records (inches, centimeters, etc). I use delegation inheritance to extend this class. See: https://www.odoo.com/documentation/9.0/howtos/backend.html#model-inheritance

So, when I add a record for newproduct.uom, a record is automatically created under the model product.uom. I can assign the values of the corresponding record in product.uom by addressing them in newproduct.uom.

For my uses, it will be intended as a Parent->child relation, with newproduct.uom being the parent, and the default product.uom being the child. I chose this method of inheritance to allow quicker creation and modification of related values, as well as a separation of functions (rather than overriding the default methods for default operations).

In your parent class override unlink. Not sure if I have the correct class name. Delete the child record and then delete the current record.

@api.multi
def unlink(self):
    self.uom_id.unlink()
    return super(new_product_uom, self).unlink()
