[Forums] how to catch a notify when I am not using a popup editor ?

Today I was creating a master/detail page using a web block as detail in the same page. When I save the detail I need to update the description in master "section". As I am using zTree I will lose the tree structure if I refresh the component. If I can capture the description using the get notify this would solve my problem. However, I only saw the on notify destination on popup editor. 
Thanks in advance for some help, people.
