Angular filter return html

I want to use unsafe-html in angularjs 1.2. Whereas the filter without html does work, with html it does not. What I do: I added angular-sanitize to my html head: ``` <script src="~/Scripts/angular.js"></script> <script src="~/Scripts/angular-sanitize.js"></script> ``` My angular module: ``` var myApp = angular.module('myApp', ['ngSanitize']) .filter('convertState', function ($sce) { return function (state) { if (state == 1) { return $sce.trustAsHtml("<strong>" + state + "</strong> special state"); } else { return $sce.trustAsHtml("<strong>"+state + "</strong> normal state"); } } }); ``` My Html: ``` <td><span ng-bind-html="f.state | convertstate"></span></td> ``` edit: updated `ng-bind-html-unsafe` to `ng-bind-html`
