Ng-Click not working in ng-bind-html

have the following code in my html page:

       <span ng-bind-html="perguntas"></span>

already in my controller have the following:

> var html = "<div ng-click="setRespostaCerta()"><a class="resposta-btn">Click Me !</a></div>";
$scope.perguntas = $sce.trustAsHtml(html);

$scope.setRespostaCerta() = function(){



When the page is loaded the button is normally displayed but when I click on it it does not work, what’s wrong?

i guess you’ve missed the ""
try alert(“click”);

in my code is correct, but not working
