Angular ng-init无法使用html元素进行分配

I have a administration corner on my web, where can Admin create and post news. It's implemented with html alements as helper. Admin clics on buttons and elements helps him, to style his text. It looks this:

I have an option to Edit existing News as well. Problem is if I try to assign this html text into my variable in ng-init It all go bad.

<h4 ng-init="TextAreaText = '<?php if ($_GET["NID"]) $Admin->DrawNewsByID($_GET["NID"]) ?>'"> Editor </h4>

It means if there is NewsID in Get, It selects News text in php and tries to assign it into TextAreaText varible.

But it is shown like this:

Because of my bad quotation marks. As you can see: - source code from my browser

Is it possible to samehow fix it? Thanks a lot.
