  app.directive('nDecimals', [nDecimals]);
    function nDecimals() {
        return {

                element.on('input', function (e) {
                  // Read the attribute to know the 'N' number places
                    var maxDecimal = Number(element.attr('n-Decimals'));
                    //Read the enetered value
                    var sal = element.val();
                    var parts;
                    if (sal.indexOf(".") !== -1) {
                        parts = sal.split(".");
                        if (parts[1].length > maxDecimal) {
                            element.val(sal.substr(0, sal.length - 1));
                // destroy event.
                scope.$on('$destroy', function () {
