JavaScript/AngularJS : How do i declare directive from from javascript?

I need to declare my html tag(angular directive) as below in javascript. How do i do with correct js syntax.

$scope.myList =[ {title='Angular1' content='<div angular-one></div>'},

                 {title='Angular2' content='<div angular-two></div>'}];

I will bind this value back to html later. I just want to know how do declare above angular-one and angular-two directives inside the div tag using javascript.

in the html, i will call the passed value from javascript and bind the directive in the html.

{{content}}

my directive get displayed as string like instead of binding as html.

It's pretty simple, all what you need it's to create a simple directive to compile the html (using the $compile service from angular):

.directive('compile', ['$compile', function ($compile) {
    return function(scope, element, attrs) {
        scope.$watch(
            function(scope) {
                // watch the 'compile' expression for changes
                return scope.$eval(attrs.compile);
            },
            function(value) {
                // when the 'compile' expression changes
                // assign it into the current DOM
                element.html(value);

                // compile the new DOM and link it to the current
                // scope.
                // NOTE: we only compile .childNodes so that
                // we don't get into infinite loop compiling ourselves
                $compile(element.contents())(scope);
            }
        );
    };
}])
