Ionic2 @ViewChild @Input @Output manipulation

Hi,
I have two components : CustomerNew (form to create new customer) and AddressNew ( form to create new customer address’s).

How can I use AddressNew component as @ViewChild in CustomerNew ?

Customer component send selectedCustomer as @Output to @ViewChild and recieve @Input newAddress
Address component (child) recieve @Input selectedCustomer and return to parent component @Output new address

Thank you in advance

I tried to use popover, but the form submitting onPrensent popover :sweat:
