Bootstrap popover content cannot changed dynamically

Question

I use the code as follows:

$(\".reply\").popover({
  content: \"Loading...\",
  placement: \"bottom\"
});

$(\".reply\").popover(\"toggle\");

Answer 1

This answer from 2012 does not work with Bootstrap 3 popovers. I extracted a working solution from this question:

$("#popover").attr('data-content', 'new content');
