Include directive before html render - html

Question

I tried wrapping my head around the following problem:
I have a html string which I render using ng-bind-html
I managed to change a given placeholder (in the html string) with a directive (or more). For example I have: [placeholder]test[/placeholder] and replaced with <my-directive></my-directive> for a certain functionality.
This approach is needed to make some content dynamic.
When rendering the html string I notice that the directive is missing, I understand, but is there a way to render it and make the directive functionally?
P.S:
Tried rendering it as a normal string but the html is escaped
Tried using $sce.trustAsHtml()
I cannot apply $compile(element.contents())(scope); since the directive is not triggered

Answer 1

I have managed to do achieve this by doing the following:
Add the directive in the html:
<my-directive update-data-trigger="someObject.content" data="someObject"></<my-directive>
The directive:
app.directive("myDirective", function ($compile) {
return {
replace:true,
restrict: "E",
scope: {
//Data holds the html in the content attribute
data: '=',
updateDataTrigger: '='
},
link: function ($scope, element) {
//Add a watcher to refresh data because the loaded data passed is async
$scope.$watch('updateDataTrigger', function(){
//Check if data passed has been loaded with our desired object
if($scope.updateDataTrigger != null) {
//Do some content manipulation here
//Append directives to the content as well
//render as html
element.html(data.content);
$compile(element.contents())($scope);
}
});
}
}
});
