AngularJS: Binding JavaScript Received in XHR to the View -


working on reporting application reports generated (in html) birt report engine object. report data comes json string recieved xhr. json string contains combination of html , javascript (a function call, specifically). once received, report data stuffed display in view. view put using angularjs.

i did research , found binding html/javascript view in angular requires use of $compile. using basis, put code include data , execute code bound string defined explicitly in $scope. - unless i'm going overlooking after staring @ same stuff couple hours, approach i'm using not work $scope data defined xhr. here's plunkr show general idea implemented. suggestions appreciated.

the html

<!doctype html> <html data-ng-app="example"> <head lang="en">     <meta charset="utf-8">     <title></title>     <link href="//maxcdn.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">     <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.10/angular.js"></script>     <script src="//cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/0.11.0/ui-bootstrap-tpls.js"></script>     <script src="//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.20/angular-sanitize.js"></script>     <script src="script.js"></script> </head> <body ng-controller="controller" >     <h1>static content</h1>     <p><button href="javascript: void(null)" role="link" ng-click="loadsubreport('recv_po_detail.rptdesign', 'static')">po000007</button></p>     <h1>html static string</h1>     <div compile="snippet"></div>     <h1>html server string</h1>     <div compile="html.body"></div>     <hr />     <button ng-click="alert()">show xhr data</button> </body> </html>

the javascript

    var app = angular.module('example', []);     app.controller('controller', ['$scope', '$compile', '$http', function ($scope, $compile, $http){         $scope.snippet="<p><button href=\"javascript: void(null)\" ng-click=\"loadsubreport('recv_po_detail.rptdesign', 'compiled')\">po000007</button></p>";         $http.get('data.json')                 .success(function (data) {                     $scope.html = data;                 });         $scope.loadsubreport = function (filename, source) {             alert("called " + source);         };         $scope.alert = function () {{           alert($scope.html.body);         }}     }]);     app.directive('compile', ['$compile', function ($compile) {                 "use strict";                 return function (scope, element, attrs) {                     var ensurecompilerunsonce = scope.$watch(                             function (scope) {                                 return scope.$eval(attrs.compile);                             },                             function (value) {                                 element.html(value);                                 $compile(element.contents())(scope);                                 ensurecompilerunsonce();                             }                     );                 };             }]);

your watch goes off right @ start, when html.body still undefined. run ensurecompilerunsonce() , unwatch scope. proper report, once loaded, never gets compiled. uncommented line ensurecompilerunsonce() , nice view of report.
