How to add plain text dynamically?

[jomadecena]

Let's say I want a "Paste" button that will paste my "plain text" from the clipboard to the editor.

If I want to do it dynamically, the text can be found on the
onValueChanged(value) { value.text[0].content[n].text = my_paste_text } where n denotes the line number
I could do it this way but it would replace the whole text line.

Motivation:
I have set of options/choices that when a user click on an option, it will add a text dynamically on my text editor
