Save Child data On parent Module after popup close action

I am showing child module of account in popup. I need to update the change in child object to parent object like if child object legal Name field is change and account name should be updated to that value. I am using after close action of popup but i am unable to get the correct value of child object legal name field populate in my account name field.

I was able to get the changed value using :

{{#Child_Object__r.records}}{{RichTextFieldName}}{{/Child_Object__r.records}}
Now I want  to run this after close action if a UI field in popup is checked.

Hi Rachit, which version of Skuid are you running? If you have Skuid Brooklyn, you may be able to pull this off using Branch logic, which would essentially check if the UI field is true, and then run the after close action.
