how to get the selectioned text from a disabled ui-select?

Question

as mentioned in the title I want to make my ui-select double clickable i.e I can get the focus on it so I can copy the content of the ui-select .

here is an example: taken from https://codepen.io/anon/pen/NYQbWb I've added the disable property the existing code.

like in this example to double click batman for example and have the possibility to Ctrl + c it or right click copy ... I've tried to add the ng-readonly but it doesn't work.

Thanks for your help in advance.

HTML:

<div ng-app="boomstrap"><div ng-controller="SelectDemoCtrl">
 <div class="row">
   <div class="form-group">
    <div class="col-sm-6">
      <ui-select ng-model="superhero.selected" disabled="true">
      <ui-select-match placeholder="Select or search a superhero ..."> 
           {{$select.selected}}</ui-select-match>
      <ui-select-choices repeat="hero in getSuperheroes($select.search) | 
         filter: $select.search">
        <div ng-bind="hero"></div>
      </ui-select-choices>
    </ui-select>
  </div>
  <label class="col-sm-3 control-label">You have chosen {{ superhero.selected }}!</label>
</div>
</div>

JS:

$scope.getSuperheroes = function(search) {
 var newSupes = $scope.superheroes.slice();
  if (search && newSupes.indexOf(search) === -1) {
    newSupes.unshift(search);
  }
  return newSupes;
}
