angular $watch 监控input值的变化

Question

<div class="pt-password-retrieval p-a" input-yemail>    <form name="inputEmail" novalidate>        <div class="yours-email">            <input type="email" name="retrievalEmail" id="retrievalEmail" placeholder="Email" class="input-pld" required ng-model="register.inputEmail" ng-focus="register.inEmailChange=false" ng-blur="register.inEmailChange=true">    </form></div>js：    routerApp.directive('inputYemail', function() {        return {            restrict: 'A',            link: function(scope, element, attrs) {                scope.$watch('register.inputEmail', function(newval, oldval) {                    console.log(newval, oldval);                });            }        };    });想在指令中实时监控input值的变化，但是没有效果，各位看看是怎么回事？

试试

scope.$watch('register.inputEmail', function(newValue, oldValue) {}, true);
