Thanks Rasika for the solution.
In the client side JS, have the following code :
<script type="text/javascript">
var protocols = *{{{protocols}}}*;
$.each(protocols, function(index, value) {
$('#queue-subscription-protocols').append($('<option>').text(value).attr('value',
index));
});
</script>
Have to use 3 curly braces.
Regards,
Hemika
