Popup script within javascript

I have a situation where I'm using the below javascript to insert a header row in a grid question. I'm now being asked to incorporate a PopUp window to some of the text in that inserted row. In the instance below the word 'feature' I'd like to have a pop up box to the .htm file listed that I have in my graphics folder. The issue here is using the SSIScript [% PopUp %] within this code. I'm not sure how to reference it properly without using the SSIScript tag. The way I have it inserted below just stops the javascript from running properly.

<code>
<script type="text/javascript">
jQuery(document).ready(function ($) {
$('#Q8_r1_row').before('<tr style="background-color: white"><td> 1. Improved search [%PopUp("features", "FeatureTesting.htm", 900, 700)%]: </td><td> <center>None</center> </td><td> <center>Low</center> </td><td> <center>Moderate</center> </td><td> <center>High</center> </td></tr>');
});
</script>
