AngularJS custom directive within ng-repeat with dynamic attributes and two way binding - angularjs

Question

I'm banging my head on the wall over this for days and finally decided to post this question since I can't find an answer that matches what I'm trying to do.
Context: I'm building a dynamic form building platform that describes form elements in a JSON structure like this -
{
"name": "email",
"type": "email",
"text": "Your Email",
"model": "user.profile.email"
}
And then in the View I have a recursive ng-repeat that includes the field template like this -
<script type="text/ng-template" id="field.html">
<div ng-if="field.type === 'email'" class="{{field.class}}">
<p translate="{{field.text}}"></p>
<input type="{{field.type}}" name="{{field.name}}" class="form-control" dyn-model="{{field.model}}">
</div>
</script>
As you see, I use a custom directive dynModel to create the ng-model attribute with interpolated value of the model from the string value. So far do good.
Now I have a more complex scenario in which I have a collection of fields that can be added or removed by clicking on Add button or removeMe button. See below -
{
"name": "urls",
"type": "collection",
"text": "Your Profile URLs",
"model": "user.profile.urls",
"items": [
{
"name": "url",
"type": "url",
"text": "Facebook URL",
"model": "url"
},
{
"name": "url",
"type": "url",
"text": "Facebook URL",
"model": "url"
}
],
"action_button": {
"name": "add",
"type": "action",
"action": "addURL"
}
}
<div ng-if="field.type === 'collection'">
<button class="btn btn-info" dyn-click click-action="{{field.action_button.action}}" click-model="{{field.model}}">{{field.action_button.text}}</button>
<div dyn-ng-repeat="item in {{field.model}}" >
<div ng-repeat="field in field.items" ng-include src="'field.html'"></div>
</div>
</div>
As you'll notice, I have another custom directive that takes care of interpolation of {{field.model}} from the previous ng-repeat (not shown).
Now to the crux of the issue. As you see in the template, I have nested ng-repeats, the first one iterates through user.profile.urls and the second one iterates through the field parameters in JSON and creates the HTML tags, etc. One of those fields is a button (action_button) that is used to add more URLS to the list. When I click the button, I want it to trigger a function in my controller and effectively add a new child to the parent model (user.profile.urls). I then also want each URL, existing and new to have a remove button next to them that will be dynamic and will remove that particular item from the model.
If you see the code above, I have a custom directive dyn-click that reads in the
click-action="{{field.action_button.action}}"
That contains the function name (addURL) to be called that resides in my controller and the model
click-model="{{field.model}}"
(user.profile.urls) to which the new item is to be added. This is not working. The reason for this complexity is that I have multiple levels of nesting and at each level there are dynamic elements that need to be interpolated and bound. The directive dyn-click looks like this right now -
exports = module.exports = function (ngModule) {
ngModule.directive("dynClick",function() {
return {
restrict: 'A',
link: function(scope,element,attrs) {
$(element).click(function(e, rowid){
scope.clickAction(scope.clickModel, scope.$index);
});
}
};
});
};
With this code, when I click on the rendered form's Add button, the code in the $(element).click method above gets executed giving the following error -
Uncaught TypeError: undefined is not a function
I have tried a few different things with scope:{} in the dyn-click directive, with different errors and none of them have worked completely with two way binding of the model and calling the function as expected.
Help!
EDIT-1 - please see the comments:
$(element).click(function(e, rowid){
scope.$eval(attrs["clickAction"])(scope.$eval(attrs["clickModel"]), scope.$index);
});
EDIT-2: The plunker is here - http://plnkr.co/edit/DoacjRnO61g4IYodPwWu?p=preview. Still tweaking it to get it right, but you guys should be able to see the necessary pieces. Thanks!
EDIT-3: Thanks Sebastian. The new plunker is here - http://plnkr.co/edit/Z6ViT7scubMxa17SFgtx?p=preview . The issue with the field.items ng-repeat still exists. For some reason the inner ng-repeat is not being executed. Any ideas? Josep, Sebastian?
