Twitter bootstrap remote modal shows same content every time

Answer 1

For Bootstrap 3, in modal.js I changed:

$(document)
  .on('show.bs.modal',  '.modal', function () { $(document.body).addClass('modal-open') })
  .on('hidden.bs.modal', '.modal', function () { $(document.body).removeClass('modal-open'); })

to

$(document)
  .on('show.bs.modal',  '.modal', function () { $(document.body).addClass('modal-open') })
  .on('hidden.bs.modal', '.modal', function () { 
    $(this).removeData('bs.modal').empty()
    $(document.body).removeClass('modal-open')
  })

(extra spacing added for clarity)

This prevents any unwanted flash of old modal content by calling empty() on the modal container as well as removing the data.
