I make Comment by Ajax but its not working - laravel

Question

I make Comment by Ajax but its not working. It can insert and I already recived the data form controller. I check alert is display but html not display.
Here is my Route: Route::post('/addComment', 'LessonController#addComment');
Here is my controller
public function addComment(Request $request)
{
$lesson_id = $request->lesson_id;
$name = $request->name;
$body= $request->body;
$comment = new Comment();
$comment->name = $name ;
$comment->body = $body;
$comment->lesson_id = $lesson_id;
$comment->save();
return response()->json($comment);
}
Here is view comment create
<div class="leave_review">
<h3 class="blog_heading_border"> Leave a Comment </h3>
{!! Form::open(['action' => 'LessonController#addComment', 'method' => 'POST', 'id' => 'comment' ]) !!}
<input type="hidden" name="_token" value="{{ csrf_token() }}" />
<input type="hidden" id="lesson_id" name="lesson_id" value="{{$lesson->id}}" />
</div>
<div class="row">
<div class="col-sm-6">
{{Form::label('name','Name')}}
{{Form::text('name', '', ['class' => 'form-group', 'id'=>'name']) }}
</div>
<div class="col-sm-12">
{{Form::label('body','Message')}}
{{Form::textarea('body', '', ['class' => 'form-group', 'id'=>'body']) }}
</div>
</div>
<div class="row">
<div class="col-md-12">
</div>
</div>
{{Form::submit('Submit', ['name'=>'submit', 'class' => 'mt_btn_yellow pull-right'])}}
{!! Form::close() !!}
<br>
Here is comment display view blade
<div id="commen_show">
#foreach ($comment as $item)
<ol class="review-lists">
<li class="comment">
<div class="activity_rounded">
<img src="/storage/Iconimage/about.png" alt="image"> </div>
<div class="comment-body">
<h4 class="text-left">{{$item->name}}
<small class="date-posted pull-right">{{$item->created_at}}</small>
</h4>
<p>{{$item->body}}</p>
Reply
<div class="clearfix"></div>
</div>
</li>
</ol>
#endforeach
</div>
</div>
Here is my javascript, I think something wrong with append
<script>
$(document).ready(function($){
$('#comment').on('submit', function(){
var lesson_id = $('#lesson_id').val();
var name = $('#name').val();
var body = $('#body').val();
var _token = $('input[name="_token"]').val();
$.ajax({
type : 'POST', // define the type of HTTP verb we want to use (POST for our form)
url : "{{url('/addComment')}}", // the url where we want to POST
data: {_token:_token, lesson_id:lesson_id, body:body, name:name},
success: function(response) {
if(response){
$('#commnet_show').prepend(
` <ol class="review-lists">
<li class="comment">
<div class="activity_rounded">
<img src="/storage/Iconimage/about.png" alt="image"> </div>
<div class="comment-body">
<h4 class="text-left">${response.name}
<small class="date-posted pull-right">${response.created_at}</small>
</h4>
<p>${response.body}</p>

<div class="clearfix"></div>

;);
}
}
});
});
});
</script>
