You created an html string with some AngularJS directives inside your link function. As you attach it to the DOM, you expect AngularJS to compile it for you, but as output you just get exactly what you wrote.
If you you use AngularJS directive in your normal html, AngularJS will compile it for you when the site is rendered.
If you create a string inside a link function of a directive, you have to do this manually. You can do this by injecting the
$compile service. You can use
$compile with either a
string or an
angular.element. This is
returning a linking function that is called with a scope. This again returns an element, which then can be inserted into the DOM.
With a string:
newElement = $compile(myString)(scope)
With an element:
newElement = $compile(angular.element)(scope)
angular.element, not a string!
What if don’t having a scope to compile it against?
Usually you would use
$compile inside a link function of a directive and there you would have a scope. If you use it for some reason somewhere else, e.g. inside a service, you could pass the scope to the function from outside. If you just need a scope, you can also just use the root scope. Inject
$rootScope and you’re ready to go.
newElement = $compile(myString)($rootScope)
