How to pass ng-model value to anchor tag which opens an HTML overlay?

I have a scenario where I display many posts on a HTML page using AngularJS and every post, when clicked, shows associated data in an overlay. Data is displayed on main page using ng-repeat tag and when any one item is clicked, HTML overlay, defined in the same page opens.

Problem:

Only first result is shown on every item i.e. whenever I click on any post with different id, it opens displaying only first id. That's incorrect. For example, if my result is:

1. Windsor hotel,
2. Chancery
3. le Merridian.

and whenever an overlay is opened, it always shows Windsor for all.

Below is the code. please suggest.::

<div ng-repeat="post in allposts" style="background-color: #f8efc0" class="col-xs-10 col-md-11">
    <div>
        <a href="http://www.jquery2dotnet.com/2013/10/google-style-login-page-desing-usign.html">{{ post.postText}}</a>
        <div class="mic-info">
