detect if the textarea value is set programmetically

Question

My website receives some text through API call and that value is displayed on textarea on the page. I want to run a function to perform some tasks after the value is set to textarea. But I don't see any event triggering when setting textarea value through program. I cannot find any related questions, solutions or articles regarding this.

Below is the demonstration of the problem I am facing.
