The following code works:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="scratch">
    <script>
        console.log("Foo");
    </script>
</div>
<script>
    $(document).ready(function () {
        setTimeout(updateScratch,2000);
    });
    function updateScratch() {
        var newHTML = '<script>console.log("Bar")</scr'+'ipt>';
        $(".scratch").html(newHTML);
    }
</script>If I run that, the console displays Foo, and two seconds later, the word Bar appears.
However, if I have the following code, it doesn't work:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="scratch">
<script src="https://static.kuula.io/embed.js"
        data-kuula="https://kuula.co/share/7PHTd?fs=0&vr=0&gyro=0&autorotate=0.47&thumbs=1&hideinst=1&chromeless=1&logo=-1"
        data-width="100%"
        data-height="500px"
        ></script>
</div>
<script>
    $(document).ready(function () {
        setTimeout(updatePanorama,10000);
    });
    function updatePanorama() {
        var newField = '7PH7S';
        var newHTML = '<script src="https://static.kuula.io/embed.js" ';
        newHTML += 'data-kuula="https://kuula.co/share/' + newField;
        newHTML += '?fs=0&vr=0&gyro=0&autorotate=0.47&thumbs=1&hideinst=1&chromeless=1&logo=-1" ';
        newHTML += 'data-width="100%" data-height="500px">';
        newHTML += "</scr"+"ipt>";
        $(".scratch").html(newHTML);
        setTimeout(updatePanorama,10000);
        console.log("Here we go again...");
        console.log(newHTML);
    }
</script>The initial panorama gets displayed. I know the function updatePanorama gets called properly, because "Here we go again..." appears every 10 seconds in the console.
Finally, using Chrome Dev Tools I can see that the scratch div contains the updated HTML.
But the script is failing to be executed the second time. I don't see the new panorama. The old one disappears, but the new one doesn't appear.
