the CKEditor is changing my html

I am using CKEditor 4.5 and it is changing my html.

For example:

If I pass in

 <article class="span3 item ">
    <a href="#" class="item-module">

        <figure class="item_img">
            <img src="thumb-4.jpg" alt="">
        </figure>
        <div class="item_content">

            <h4>ertyasasety Lytarse</h4>
             <p>seplabrde ertyasasety kertyas</p>

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

it changes it to

<article class="span3 item ">
	<figure class="item_img"><a class="item-module" href="#"><img alt="" src="thumb-4.jpg" /> </a></figure>

	<div class="item_content">
		<h4><a class="item-module" href="#">ertyasasety Lytarse</a></h4>

		<p><a class="item-module" href="#">seplabrde ertyasasety kertyas</a></p>
	</div>

	<div class="clearfix">&nbsp;</div>
</article>

This code is not work like the original

Is there a way to i have the right html code?

my config.js have

    config.templates_replaceContent = false;
    config.allowedContent = true;
    CKEDITOR.dtd.$removeEmpty['span'] = false;
    CKEDITOR.dtd.$removeEmpty.i = 0;
