Can't seem to bind event handlers to directive-generated markup in Angular.js

Question

I'm attempting to bind an event handler to elements that don't yet exist within the DOM but am running into issues. I think where the problem begins is at line #51, where I attempt to find an element that doesn't exist (because ng-repeat hasn't yet generated it). Is there a way around this without creating a binding that is too general (e.g., $("a").on("click", function () {});)?

The angular way could be something like

var app = angular.module('my-app', [], function() {

})

app.controller('AppController', function($scope) {

  $scope.message = "Welcome";
})
app.directive("coverPhotoCarousel", ["$compile",
  function($compile) {
    return {
      restrict: "EA",
      replace: true,
      templateUrl: "cover-photo-carousel.html",
      scope: true,
      controller: function($scope) {
        $scope.images = [{
          title: "",
          url: "http://placehold.it/90&text=abc",
          description: "",
          cover: true
        }, {
          title: "",
          url: "http://placehold.it/90&text=def",
          description: ""
        }, {
          title: "",
          url: "http://placehold.it/90&text=ghi",
          description: ""
        }, {
          title: "",
          url: "http://placehold.it/90&text=jkl",
          description: ""
        }];
        $scope.bark = function() {
          console.log("Something.");
        };
        $scope.myStyle = {};
        $scope.clicked = function(image) {
          $scope.myStyle['background-image'] = 'url(' + image.url + ')'
        }
      },
      link: function(scope, element, attributes) {

        if (scope.images.length > 1) {
          element.find(".cover-photo-control .glyphicon").show();
        }

        scope.images.forEach(function(value, index) {
          if (value.cover) {
            element.css({
              "background-image": "url(" + value.url + ")"
            });
          }
        });

        element.find(".thumbnails-container .thumbnails ul li a").on("click", function(e) {
          e.preventDefault();
          element.css({
            "background-image": "url(" + scope.images[1].url + ")"
          });
        });
      }
    }
  }
]);

.cover-photo-carousel {
  background-repeat: no-repeat;
  background-position: center center;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="my-app" ng-controller="AppController">

  <cover-photo-carousel></cover-photo-carousel>

              <a href="#" ng-click="clicked(image)">
                <img src="{{image.url}}" alt="" width="90" />
              </a>
            </li>
          </ul>
        </div>
      </div>
    </div>
  </script>

Use ng-click to execute click handlers in AngularJS.
