Before explaining why your code, as written doesn’t work, and how to fix it, can you give some background as to why you are doing it this way?
Unless you are trying to write a tool similar to Keyboard Maestro, you probably don’t want to be doing it this way.
- In general, you probably want to modify the model objects programmatically, and have the views react and update their display values.
- In the case that you want to update the views directly, you really ought to be reading the value from the pasteboard and setting the view’s display value programatically.
If this really is an academic exercise in pulling puppet strings on the UI, and you have legitimate reasons for doing so, including them in the original question would have avoided the speculation about why you are doing something which seems superficially crazy.

Problem #1:
You change the first responder to sending -makeFirstResponder: to the window. It may fail if editing could not be committed for he current editor.

Problem #2a:
This code assumes that your window is the key window and the application is frontmost.
Problem #2b:
You have posted an event, but until AppKit dequeues the event and processes it, the paste doesn’t actually happen. This is why you eventually get 3 pastes in the last edit field.
