Utilizing JavaScript in Angular to dynamically add a tag with interpolation

My current testing routine involves using Javascript to create a div element, append it to the body, and then set its innerHTML property to:

<p>{{testVar}}</p>

The code I use looks like this:

var created = document.createElement('h1');

var elem = document.body.appendChild(created);
elem.innerHTML='<p>{{testVar}}</p>';

However, when the element is displayed on the page, the double curly brackets are not being interpreted correctly. How can I dynamically add this single element to my page in a way that recognizes the interpolation?

To properly render the HTML within the scope, you need to utilize a directive:

app.directive("renderDynamicHtml", ["$compile", function($compile) {
    return {
        restrict: "A",
        link: function(scope, element, attributes) {
            var compiledContent = $compile("<h2><p>{{dynamicText}}</p></h2>")(scope);
            document.body.appendChild(compiledContent);
        }
    };
}]);
