   app.directive('validEn', function () {
        return {
            require: '?ngModel',
            link: function (scope, element, attrs, ngModelCtrl, SweetAlert) {

                ngModelCtrl.$parsers.push(function (val) {
                    var clean = val.replace(/[^a-z|^A-z|^\s]+/g, '');
                    console.log("sfdsfd")
                    if (val !== clean) {
                        ngModelCtrl.$setViewValue(clean);
                        ngModelCtrl.$render();

                    }
                });
            }
        };
    });

You need to change your regex statement so that it replaces any numerics with empty string, as such:

var clean = val.replace(/\d*/g, '');
