How do I add a script inside the game's DOM?

Hello,

I have AdSense script I want to add to the game's DOM on start of layout. I used javascript script to do that.

It works in preview and the code shows when I view source, but no ads show up.

When the game is uploaded to the server, I get this text in the source instead of the script that was correctly shown in preview:

<noscript>
		<div id="notSupportedWrap">
			<h2 id="notSupportedTitle">This content requires JavaScript</h2>
			<p class="notSupportedMessage">JavaScript appears to be disabled. Please enable it to view this content.</p>
		</div>
	</noscript>
