I am caching a footer – I call get_template_part and cache the contents.
But the footer has a script file enqueued in functions.php.

That script does not get included in the cached content.
Here is the caching:

ob_start();

 get_template_part(
    $templatePathSlug, 
    null,
    $variablesArray
 ); 
 $cacheData = ob_get_clean();

The $cacheData does not have the enqueued stuff, since I guess that is added later when the page loads(?)

Can I get it to include the enqueued files directly when calling get_template_part ?
Or is there some other way?
