Video clicks count laravel - laravel

Question

I am trying to count the number of clicks on my video using Laravel. I followed this tutorial I found on Google: http://cameronscott.co/posts/tracking-page-clicks-in-laravel but nothing is working. I clicked on the video and it didn't increment in the database. Here is my code.
Route:
Route::get('video/{id}/click','ClickController#clickvideo');
Controller:
class ClickController extends Controller
{
public function clickvideo($id){
$po=User::findorfail($id);
$po->increment('clicks');
$po->update();
}
Views:
<a href="{{url('video/{$proo->id}/click')}}" class="js-click-video" style="border:none; background:none;">
<video class="video1" id="cb" preload="auto" data-post-id="{$proo->id}" style=" overflow: hidden; width: 30vh; object-fit: cover; float:left; clear:both;
height: auto; padding-left:2%; margin-top:0px; border:2px solid white; cursor:pointer; "><source src="{{$proo->intro_video}}#t=13" playsinline alt="Video Unavailable" id="" ></source>
</a>
JavaScript:
$('.js-click-video').click(function(e){
e.preventDefault();
var post=$(this).closest('.video1');
var postId=post.attr('data-post-id');
registerPostClick(postid);
});
function registerPostClick(postid){
$.ajaxSetup({
headers:{
'X-CSRF-TOKEN' : $('meta[name="_token"]').attr('content')
}
})
$.ajax({
type: 'post',
dataType: 'JSON',
url: '/video/' + postId + '/click',
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr.status);
console.log(JSON.stringify(xhr.responseText));
}
});
}

You are missing a mustache in your variable name here:
data-post-id="{$proo->id}"
Should be
data-post-id="{{$proo->id}}"
This should also be:
*{{url('video/{$proo->id}/click')}}*
{{url('video/' . $proo->id .'/click')}}
Also, this is not necessary
$po->update();
