How to turn Off Tiny_MCE in Custom-Promo-Block?

Dear Community,

i've encountered a problem with the Tiny_MCE Wysiwyg-Editor in the basic-setting.

I was trying to implement an java-script driven Promoblock that looks somehow like this:

1. <div id="myCarousel" class="carousel slide">
2. <ol class="carousel-indicators">
3. <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
4. <li data-target="#myCarousel" data-slide-to="1"></li>
5. <li data-target="#myCarousel" data-slide-to="2"></li>
6. </ol>
7. <!-- Carousel items -->
8. <div class="carousel-inner">
9. <div class="active item">…</div>
10. <div class="item">…</div>
11. <div class="item">…</div>
12. </div>
13. <!-- Carousel nav -->
14. <a class="carousel-control left" href="#myCarousel" data-slide="prev">&lsaquo;</a>
15. <a class="carousel-control right" href="#myCarousel" data-slide="next">&rsaquo;</a>
16. </div>

(This is taken from the bootstrap-framework)

Unfortunately the WYSIWIG-HTML-Editor cleans up the code and therefore the data-slide-to argument simply is gone after i try to save this.

As i don't know how to turn this off, i just wanted to get rid of this WYSIWIG ;)

Does anyone know how to achieve this?

Best regards
