This is a shortcoming of the Bootstrap modal design. In Bootstrap 3
documentation, they say that being able to reload a modal with different
content is deprecated, and in Bootstrap 4, they are going to remove the
possibility (IIRC). The docs mention that if you want to do something like
this, you should use a client-side framework (I am not a fan of this idea).
Here's what I use in Bootstrap 3 to work around this:
$(document).on('page:change', function(){
// shims for the Bootstrap Modal, which is bloody-minded about caching
content per modal
$(document).on('click', '#reusable_modal [data-dismiss="modal"]', function
(e) {
$(e.target).removeData('bs.modal');
$('#reusable_modal .modal-content').empty();
});
$(document).on('click', '[data-target="#reusable_modal"]', function(e) {
$("#reusable_modal .modal-content").load($(this).attr("href"));
});
});
