javascript - How to reference a module variable in an expression? -

i have module , it's variable defined this

var app = angular.module('app',[]); app.value(     'image',     {         id: null,         url: null,     } );

in module controller set variable value later on after ajax call. actual value of variable set correctly check controller after call.

i try reference variable html code this

<html ng-app="app"> ... <img ng-src="{{app.image.url}}">

for reason expression evaluated empty string. doing wrong?

this happens because app not defined in $scope, have set it:

angular.module('app').controller('somecontroller', function(image) {     $scope.image = image; });

then in view:

<html ng-app="app" ng-controller="somecontroller"> ... <img ng-src="{{image.url}}">
