Why is the DIV not inserted but only the IMG ?

```
$(document).ready(function() {

    $(document).on('click', '#insertImage', function(){

        /*
        Why is the DIV not inserted ?
        */
         var item = "<div class='resizable'><img src='http://www.rockiesventureclub.org/wp-content/uploads/2013/02/flower-icon.png'></div>";
         document.execCommand('insertHTML', false,item);

    })
});

```
