JavaScript: Dynamically created html-like string won't tun into html

Question

in DOM I already have a wrapper

<div id="wrapper"></div>

which I need to fill with bunch of divs, where each will represent new category. Each category will be then filled with various cards representing items of that category. Like this:

<div id="wrapper">
  <div data-category="puppy">
    Dynamically created category wrapper
    <div class="puppy1">...</div>
    <div class="puppy2">...</div>
  </div>
  <div data-category="cat">
    ...
  </div>
</div>

I use following code to create and fill category, but I always end up either having empty category or having a string inside reprenting the html.

var categoryWrapper = document.createElement("div");
categoryWrapper.setAttribute("data-category", key);
categoryWrapper.innerHtml = htmlString;

Here is a fiddle demo of my issue. https://jsfiddle.net/uuqj4ad5/

I'll be grateful for a help.

There is a typo, innerHml should be innerHTML(Javascript object properties are case sensitive) otherwise it simply add an additional property and nothing gets happened.

categoryWrapper.innerHTML = htmlString;

var htmlString = "<div class='card'><div class='cardImg'><img src='http://cdn.cutestpaw.com/wp-content/uploads/2012/07/l-Wittle-puppy-yawning.jpg' alt='Puppy'></div><div class='cardContent'><div class='cardInfo'><p>Puppy Yawning</p></div><div class='cardDesc'><p>Awww!</p></div></div></div>";

var outerWrapper = $("#wrapper");
var categoryWrapper = document.createElement("div");
categoryWrapper.innerHTML = htmlString;
outerWrapper.append(categoryWrapper);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
  <h3>
    Under this title various categories should be dynamically created
  </h3>
  <div id="wrapper">outerWrapper waiting for dynamic data...</div>
</div>

FYI : If you want to remove the existing content then use html() method instead of append() method.
