title: Only Internet explorer doesn't allow my code
body: <p>I have a problem with Internet Explorer and HTML code. In Chrome, Edge and Firefox all works fine, but in Internet Explorer I have this problem displayed in the picture below:</p>
  
  <p>The initial state,

  <p>and when I click the plus button</p>

  <p>instead of</p>
  
  <p><a href="https://i.stack.imgur.com/M8BIh.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/M8BIh.jpg" alt="enter image description here"></a></p>
  
  <p>I found where the error is located, it is in datatable javascript:</p>
  
  <pre><code>data:null, render: function ( data, type, row ) {
      var user;
      var s="";
      for (user in row.users)
      s += '&lt;span class="tag label label-info"&gt;&lt;span&gt;'+row.users[user]+'&lt;/span&gt;&lt;a&gt;'
      +'&lt;i id="deleteUserFleet" data-toggle="modal" data-application="'+row.application+'" data-fleet="'+row.idFleet+'" data-id="'+row.users[user]+'" data-target="#deleteUserFleetModal" class="remove glyphicon glyphicon-remove-sign glyphicon-white"&gt;&lt;/i&gt;&lt;/a&gt;&lt;/span&gt;';
      return s;
  }
  </code></pre>
  
  <p>If I use return 'hello' all works fine, but there is an error in my above code that only Internet Explorer found. Do you know what is the problem? Thanks</p>
