Laravel - cross domain request - barryvdh laravel-cors

I have problem with cross domain request. I want to send get request via ajax from 'www.second-domain.com' to 'www.first-domain.com/path/to/plugin' and return html code (plugin view).
I install 'barryvdh/laravel-cors' from github in Laravel 4.2 on 'www.first-domain.com'.

plugin.blade.php

<div id="bookingPlugin"> <div class="container"> <div class="bookingPlugin"> <div class="bookingPluginHeader"> <div class="bookingPluginTxtCenter">REZERWACJA ON-LINE</div> </div> <div class="bookingPluginContent bookingPluginNoPadding"> @foreach ($categories as $category) <div class="bookingPluginButtonContainer"> <button id="{{{ $category->CategoryId }}}" class="bookingPluginTxtCenter">{{{ $category->CategoryName }}}</button> </div> @endforeach </div> </div> </div> </div> <div id="bookingWindow"></div> <script> $.getScript('http://plugins.first-domain.com/bookingWindow.js'); $.getScript('http://first-domain.com/packages/jquery-ui/jquery-ui.min.js'); $("head").append( "<link href=\"http://first-domain.com/packages/jquery-ui/jquery-ui.min.css\" rel=\"stylesheet\" media=\"all\" type=\"text/css\">" ); $("#bookingPlugin button").click(function(){ openBookingWindow("{{ $hotelId }}", this.id); }); </script> 

On 'www.second-domain.com' I added the following line to the code. If this line I added to 'www.first-domain.com' it is working.

<script type="text/javascript" src="http://plugins.first-domain.com/book.js"></script> 

book.js

$("head").append( "<style>"+ "#bookingPlugin{position:absolute;top:200px;width:100%;z-index:999;}"+ "#bookingPlugin button{font-size:100%;margin:0;vertical-align:baseline;line-height:normal;text-transform:uppercase;background:#2670b5;}"+ "#bookingPlugin button{width:100%;cursor:pointer;color:#fff;-webkit-appearance:button;border:1px solid #fff;outline:0;padding:5px;}"+ "#bookingPlugin button:hover{background:#275DA2}"+ ".bookingPlugin{width:250px;background-color:#fff;color:#444;border:1px solid #fff;padding:5px}"+ ".bookingPluginNoPadding{padding:0;}"+ ".bookingPluginHeader{width:100%;font-weight:bold;border-bottom:1px dotted #444;margin:0 0 5px 0;padding:5px;}"+ ".bookingPluginTxtCenter{text-align:center;}"+ ".bookingPluginContent{width:100%;}"+ ".bookingPluginButtonContainer{width:100%;}"+ "</style>" ); $.ajax({ //send get ajax request to laravel type:'get', //call to route url:'http://www.first-domain.com/path/to/plugin', //return data type as html dataType:'html' }).done(function(data){ //insert returned data into body element $("body").append(data); }).fail(function(jqXHR, ajaxOptions, thrownError){ alert(thrownError); });
