Angularjs directive adds directives as an attribute and binds them dynamically

Hi, I am working on a directive where I need to edit the DOM by adding the ng-src attribute and model to it.

This is my DOM

     <edit-component>
      <img src="images/logo.png" title="Hearty Wear" />
    </edit-component>

I need a DOM be result

       `<div>
         <img src="images/logo.png" title="Hearty Wear" ng-src={{myModel}} />
       </div> `

That way, when I update myModel with data, the image should be updated

UPDATE

sam.directive('editComponent', function() { return { restrict: 'EA', transclude: true, replace: true, templateUrl: "imageTemplate.html", link: function(scope, element, attb, ctrl, transclude) { scope.data = function() { var imagedata; imagedata = arguments[5]; scope.imageModel = imagedata.base64; return element.find('img').attr('src', "data:image/png;base64," + imagedata.base64); }; } }; });

I need the previous src attribute value to display an existing image.

I am currently updating the src attribute manually. I need a solution where I can update using the model variable

thank

AngularJS .

→ → preLink → postLink ()

angular (ng-model, ng-style, ng-src) <

var app;

app = angular.module('App', []);

app.directive('myDirective', [
  '$compile', function($compile) {  // Crucial Part
    return {
      scope: true,
      compile: function(element, attrs) {
        element.attr('ng-src', '{{imageModel}}');
        element.attr('ng-click', 'updateImage()');
        element.removeAttr('my-directive'); // Crucial Part
        return {
          pre: function(scope, ele, attb) {},
          post: function(scope, ele, attb) {
            $compile(ele)(scope);
            return scope.updateImage = function() {
              return scope.imageModel = "http://www.google.com/logos/doodles/2015/halet-cambels-99th-birthday-6544342839721984-hp2x.png";
