Populate data into standard component alv from Zcomponent popup data selected

HI All

I have to call Zcomponent in standard component and need to pass value into Zcomponent (table) and from  Zcomponent select row and pass back to standard component.

Steps

1) Created Zcomponent with interface node

2) Enhanced the standard component and create used components for  Zcomponent and make it available at component controllers and view controllers.

When I click on Button in standard component I am calling this Zcomponent as popup window.

My problem I when I select data in Zcomponent I need to populate the data in ALV of standard component.

I thought of 2 methods to take my selected back and populate data into standard component ALV.

1) Create event: EVENT1 and   Interface method Method1 and link to EVENT1

So that I can raise this event in Zcomponent and populate the data into standard component ALV

Problem: Under events interface checkbox is visible, when I select my enhancement implementation the interface checkbox not visible under events tab?.

2) Create Interface method Method1 write logic topopulate data into standard component ALV

But here to when I select my enhancement implementation the interface checkbox not visible under?

Can anyone please help me why interface checkbox is not visible or any better solution to populate the data back to standard component alv?

Thanks
