adding tinyMCE to a text area added via ajax

I am developing a plugin that uses an ajax powered add button to add a textarea (or 20 if you desire) that uses the class=”theEditor” to display the built in TinyMCE toolbar

It’s not showing unless the post is saved and then it all works fine.

I am not an ajax expert by any means, so I’m stumped as to how to include tinyMCE via ajax.

can anyone offer a solution?

thanks,
Elle
