Wordpress: add events inside TinyMCE iframe

Question

I've added some div wrapper styles to Wordpress, but when I use them in the page, it is impossible to add content below them in the page. CSS:after works inside the divs to create a selectable area, but it doesn't work to create a selectable area after the div.

In my functions.php I have:

  function my_mce_before_init( $settings ) {
    $style_formats = array(
        array(
            'title' => 'Box Two Columns',
            'block' => 'div',
            'classes' => 'twocolbox',
            'wrapper' => true
        ),
        array(
            'title' => 'Image with Caption',
            'block' => 'div',
            'classes' => 'img_caption',
            'wrapper' => true
        ),
        array(
            'title' => 'Gallery Horizontal',
            'block' => 'div',
            'classes' => 'scroller horizontal',
            'wrapper' => true
        )
    );

    $settings['style_formats'] = json_encode( $style_formats );
    return $settings;

}
add_filter('tiny_mce_before_init', 'my_mce_before_init');
add_editor_style();

Is there a way to use execCommand here to add some html after the div styles I defined? To add something like an empty paragraph tag afterwards with a clear float?

I tried:

tinyMCE.execCommand('mceInsertContent',false,'Hello world!!');"

MCE editor breaks then.

... Tried this but it's too buggy: In editor-styles.css:

#tinyMCE:after {
 content: "    ";
 clear:both;
 width: 4em; height:4em;
}

Note that you may need to clear cache AND shift-reload button to see any changes to editor-styles.css in Wordpress.

...

Still working on this. Found a thread: To access tinymce iframe elements through jquery

I tried adding the code in this thread to my_mce_before_init, but it just broke.

.... Also tried loading a jQuery script, but the target paths wouldn't work on the TinyMCE iframe. None of these selectors work:

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

    $("#tinyMCE").find("div").after('<p style="width:100%; clear:both; height:1em;">&nbsp; 6789</p>');
     $("div").css("color","red");

    $("#content_ifr").contents().find("div").after('<p style="width:100%; clear:both; height:1em;">&nbsp; 6789</p>');
    $("#content_ifr").contents().find("#tinymce p").css("color","red");

    $("#wp-content-editor-container").find("textarea").css("color","red");
    $("iframe").contents().find("p").css("color","red");

    $('#content_ifr').load(function(){
        $('#content_ifr').contents().find('p').css("color","red");
    });
 });

You can add html pseudo elements using the tinymce configuration option content_css. There you can define after elements. Give it a try!

Update:

When initializing tinymce set the setup paramter to the following (inside tinyMCE.init({...})

...
theme: "advanced",   // example param
setup : function(ed) {
    ed.onInit.add(function(ed, evt) {
        $("#content_ifr").contents().find("p").css("color","red");

        // other approach  
        //$(ed.getBody()).find('p').css("color","red");
    });
},
cleanup: true,      // example param
...
