Is there any way to call a wizard after creating an object in odoo11? or perhaps use some sort of after_create method?

I've tried this code but it doesn't seem to work

@api.model

def create(self, values):

    a= super(MyModel, self).create(values) 

    self.open_wizard()

    return a

def open_wizard(self):
    return {
	'name': 'my wizard',
	'type': 'ir.actions.act_window',
	'res_model': 'my.wizard',
	'view_type': 'form',
	'view_mode': 'form',
	'target': 'new'}
