Using <select> and <option> in AngularJS

I have this anchor tag and i change my view depending on the date coming from the object. I am trying to change it to be a select option but it is not working the way i am doing it.

This is anchor tag syntax:

 <a href="#" ng-repeat="item in home.prData" ng-click="home.selectedPr = item; $event.preventDefault();
 $event.stopPropagation();">{{item.date}}</a>

I am trying to change it to be like that when i use select option

 <select st-search="{{item.date}}" class="show-tick form-control dropdown_custom_list">
      <option value="">- select a date -</option>
      <option ng-repeat="item in home.prData" value="{{home.selectedPr = item}}">{{item.date}}
      </option>
  </select>

i created an example plunkr to what i am trying to achieve:
