Using isConfirm with a SweetAlert

I have a SweetAlert with a Cancel option.  My javascript has the isConfirm function and works correctly if isConfirm is true.  It just bypasses the code for the else statement. Any thoughts?

 swal({
                title: "Add New Action/Task",
                text: "This will add a new Action/Task to the stored Action List for future use.  If you do not wish to save this Action for later, click Cancel and choose Other.",
                type: "warning",
                showCancelButton: true,
                cancelButtonText: "Cancel",
                buttons: true,
                dangerMode: true,
                closeOnConfirm: true,
                closeOnCancel: true,
                confirmButtonText: "Yes"
            },
                function (isConfirm) {

                    if (isConfirm) {
                        CM.disabled = false;
                        CM.style.backgroundColor = "white";
                        actionOther.style.backgroundColor = "white";
                        actionOther.placeholder = "Enter New Action/Task";
                    }

                    else {
                        CM.disabled = false;
                        actionDropdown.value = "Other";
                        actionDropdown.text = "Other (Enter Other Action/Task)";
                        actionOther.placeholder = "Enter Other Action/Task";
                    }

                }.bind(this));
