Dart call JQuery select2

Question

I am working with Dart and JQuery. In the view I try to use select2 for a ComboBox component,my code is:

<div class="form-group">
  <label class="control-label col-md-3 col-sm-3 col-xs-12">Select</label>
  <div class="col-md-9 col-sm-9 col-xs-12">
   <select class="select_cities form-control" tabindex="-1">
    <option value="NY">New York</option>
    <option value="LA">Los Angeles</option>
    <option value="CH">Chicago</option>
    <option value="HO">Houston</option>
    <option value="PH">Phoenix</option>
   </select>
  </div>
</div>
...
<script>
  $(document).ready(function () {
     $(".select_cities").select2({
        placeholder: "Select a City",
        allowClear: true
      });
   });
</script>

My question is, how can I call this function in Dart? because when the view is loaded the select_cities component doesn't work, I suppose that every jquery function has to be called in Dart file.

Thanks for all
