javascript - protractor executeScript doesnot run the function -

im trying post api using registration page , have used $http request post data

 it('login page patient dashboard existing email , password', function() {         console.log('entering login page')             browser.get('http://localhost:9000/login.html');         browser.executescript(function(callback) {             var $http;             $http = angular.injector(["ng"]).get("$http");             console.log('http request')             return $http({                 url: "http://int.eclinic247.com/reg/create-patient",                 method: "post",                 data: {"firstname":"jya","lastname":"raq"},                 datatype: "json"             }).success(function() {                 return callback([true]);                 console.log('done')             }).error(function(data, status) {                 return callback([false, data, status]);                  console.log('oops not done!!!!')             });         })     element(by.model(objects.locators.passwordbox)).sendkeys(objects.login.password);
