angular js: Prevent Bootstrap Modal from disappearing when clicking outside or pressing escape?

Use:

backdrop: 'static'

backdrop – controls presence of a backdrop. Allowed values: true
(default), false (no backdrop), ‘static’ – backdrop is present but
modal window is not closed when clicking outside of the modal window.

For example:

$modal.open({
      templateUrl: 'myModalContent.html',
      controller: ModalInstanceCtrl,
      backdrop: 'static'
    })
