Indesign Script Js: Edit Document Textframe Content And Get Back To Dialog Window

I want to edit some textframe content in Indesign documents by JS. But I cannot find any solution to get any change with feedback in Dialog Window. So I just have a simple document

Solution 1:

To keep your custom window and UI access define this window as "palette" instead of "dialog". Your script 1st directive supposes to call your custom targetengine as well, something like: #targetengine "mysession"
