Summer Note Issue in Bootstrap modal

Question

I am using the Summernote Text plugin inside my project. But it seems to be not working properly. The editable inside the Summernote doesn't show any text which I am typing. It only shows text when I resize the window in the browser. I am including the code below; I hope it helps.

 <%-- Rendering modal--%>
<div id="TCModal" class="modal animated fadeIn" role="dialog">
   <div class="modal-dialog modal-dialog-w-lg">
      <!-- Modal content-->
      <div class="modal-content">
         <div class="modal-header">
            <button type="button" class="close text-inverse" style="opacity: .5" data-dismiss="modal" aria-hidden="true"><i class="ion-close-circled"></i></button>
            <h4 class="modal-title">Type Your Terms & Conditions &nbsp;</h4>
         </div>
         <div class="">
            <div style="max-height: 500px" id="summernoteTermsAndCondition">
            </div>
         </div>
      </div>
   </div>
</div>

And the initialization for summer note is

 $('#summernoteTermsAndCondition').summernote({
            placeholder: '',
            height: 200,
            popover: {
                air: [
                  ['color', ['color']],
                  ['font', ['bold', 'underline', 'clear']]
                ]
            }
        });

In this case modal create after DOM so you need to initialize or re-initialize summernote after modal open:

$('#myModal').on('shown.bs.modal', function() {
  $('#summernote').summernote();
})

<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>

<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <div id="summernote">Hello Summernote</div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>

Or use dialogsInBody: trueor airMode: true

$('#summernote').summernote({
  dialogsInBody: true
  //,airMode: true
});
