Not sure I understand what you mean. Did you have something like this?

<div id-"change-div"> <div id="text2">2...</div> <div id="text3">3...</div> </div>

In other words, is the source of the text that you're copying to change-div nested within change-div to begin with? If so, that would cause a problem because after the first call, the source would no longer exist. In other words, after the first call, your DOM would become:

<div id-"change-div"> 2... </div>

Therefore, subsequent button clicks would result in this:

var htmlStr = ( "#text2" ).html(); // htmlStr = null because #text2 no longer exists in the DOM
