Callback cancel is missing

In some cases, to access resources that are wrapper maybe will want to make accessible in swal callback when it is triggered.
To do this, we use the known .bind()
swal({ title: "Are you sure?", text: "You will not be able to recover this imaginary file!", type: "warning", showCancelButton: true, confirmButtonClass: "btn-danger", confirmButtonText: "Yes, delete it!", cancelButtonText: "No, cancel plx!", closeOnConfirm: false, closeOnCancel: false }, (function(isConfirm) { debugger; if (isConfirm) { swal("Deleted!", "Your imaginary file has been deleted.", "success"); } else { swal("Cancelled", "Your imaginary file is safe :)", "error"); } }).bind());
But when used this technique, in case of cancel, the callback is never called, only when confirm.

I have tracked the issue, it's caused by the check imposed in dev/modules/handle-click.js line 84, where it only calls the callback if it pass in a regex to ensure the presence of a parameter in function passed. In case the callback is a result of .bind() when passed to .toString() it miss all original function code and returns:
function () { [native code] }
