smartgrid linked table edit returns to main table listing and not to the linked table listing

[icodk]

 smartgrid that shows list of parents from a parents table and a Children  linked table. Clicking on the Children link on a specific parent line shows a list of children's of that parent.

So far so good. 

Click on the edit button on specific child in the list  I can edit this child.

Finish editing by submitting the edit form of the child takes me back to the parent list and not to the list of children where I was just before I started editing specific child.

How can I get back to the list of children of the parent instead of to the parents list after editing  a child record?
