I have encountered a problem where I am attempting to add a DOM node when a custom button is clicked, but the model associated with the textarea is not being properly updated.
To illustrate the issue, I have created a plunker as a demo.

If you click on the 'My Button' multiple times, you will notice that the model stops updating after the initial click.
Thank you in advance for any help, and I hope my question is clear.
