Avoiding state transitions within Angular's ui-router from within a directive

One of the challenges I am facing involves a directive called clickable-tag, where I pass my data as the tag's name (tag.tag):

<a class="item item-avatar"
   ui-sref="nebula.questionData({questionId: question.id})"
   ng-repeat="question in questionsData.questions">
    <img src="{{question.user.profile_photo || '../img/avatar.jpg'}}">
    <h2 class="question-title">{{question.title}}</h2>
    <p>{{question.description}}</p>
    <div class="question-tags-list" ng-repeat="tag in question.tags" clickable-tag data="{{tag.tag}}">
        <button type="submit" class="tag">{{tag.tag}}</button>
    </div>
</a>

While using the clickable-tag directive within a ui-sref (on the outer a tag), I aim to prevent the default behavior and instead redirect users to another specified state:

.directive("clickableTag", function($state) {
  return {
    restrict: "A",
    scope: {
      data: "@"
    },
    link: function(scope, elem, attrs) {
      elem.bind('click', function(ev) {
        console.log('scope.tagName: ', scope.tagName);
        if (scope.data) {
          $state.go('nebula.tagData', {tagName: scope.data});
        }
      });
    }
  };
})

An issue arises where only the resolve of the state mentioned inside the directive is executed. The view rendered belongs to the state defined by the outer ui-sref.

I am seeking possible solutions to prevent the triggering of the outer ui-sref and initiate a state change as indicated within the directive.

Your assistance in resolving this matter would be greatly appreciated. Thank you.

Please note: Attempts have been made using preventDefault(), stopPropagation(), and return false within the directive without success.

Make sure to place the ng-repeat above the <a> element and close the <a> tag before the button.

<div ng-repeat="item in items">

   <a class="item item-avatar"
        ui-sref="app.itemDetail({itemId: item.id})">

       <img src="{{item.image || 'placeholder.jpg'}}">
       <h2 class="item-title">{{item.title}}</h2>
       <p>{{item.description}}</p>
   </a>  <!--Close A tag here --->

   <div class="tags-list" ng-repeat="tag in item.tags"
             ng-click="$state.go('app.tagDetail', {tagName: tag.name})">

       <button type="submit" class="tag">{{tag.name}}</button>

   </div>
</div>
