I have a simple onchange function in which I am writing to a few fields. But the value returned as "vals" isn't getting to the frontend. The values returned in the network tab for Here is the function:

	@api.multi
	@api.onchange('email')
	def onchange_email(self):
		vals = {}
		contactid = ""
		siteid = ""
		respartner = self.env['res.partner'].search([('id','=',self._origin.id)])
		for partner in respartner:
			for site in partner.company_site_lines:
				if site.company_corporate:
					site.email = self.email.upper()
					site.write({"email":self.email.upper()})
			for contact in partner.contact_ids:
				if contact.flag_first_contact:
					contactid = contact.id
					contact.email = self.email.upper()
					contact.site_email = self.email.upper()
					contact.write({'email':self.email.upper(),'site_email':self.email.upper()})
					self.write({'contact_ids':[(1,contact.id,{'email':self.email.upper(),'site_email':self.email.upper()})]})
			partner.email = self.email.upper()
			partner.write({'email':self.email.upper()})
			vals['email'] = partner.email
			vals['active_tabs'] = partner.active_tabs
			ressite = self.env['company.site'].search([('company_site_id','=',partner.id)])
			vals['contact_ids'] = self._origin.contact_ids
                        #Printing vals['contact_ids'] gives the proper one2many field with the correct id: partner.contact(475,)
                        #But the output in chrome is:
#	{"jsonrpc": "2.0",
#	"id": 427040437,
#	"result": {
#		"value": {
#			"contact_ids": [
#				[5]
#			],
#  		 .
#                .
#                .
#                .
	    return {'value':vals}

# Is there something wrong with the way I am returning Values?
