Wordpress tinyMCE keep adding <p> tags when I saved my custom post types in visual mode opened!

I had searching for many solutions, but not working. Here is the solution that I found, but this is unable to stop wordpress from adding annoying <p> tags from my html codes:

Javascript:

<script type="text/javascript">
     tinyMCE.init({force_p_newlines : false});
</script>

PHP

function tinymce_remove_root_block_tag( $init ) {
    $init['wpautop'] = false; 
    $init['force_p_newlines'] = false; 
    $init['forced_root_block'] = false; 
    return $init;
}
add_filter( 'tiny_mce_before_init', 'tinymce_remove_root_block_tag' );

I don't want any kind of solution which is using the_content hook, because this is still letting <p> tags inside wordpress text editor. Example:

remove_filter ("the_content", "wpautop");

What else should I use to stop tiniMCE from messing up html codes with its auto added <p> tags?
