need to disable the Paste ability

[KenHanks]

I need to disable the Paste ability. I've been able to disable the buttons by removing their definitions from the js files. I also have this jquery command:

     $doc.on("paste",function(e) {
        e.preventDefault();
        return false;  
    });

And this one:

    $('#my_text_area).on('paste',function(e) {
        e.preventDefault();
        return false;  
    });

Neither of these prevent the "CTRL-V" or right-click ability to paste.

Does anyone have any ideas on how I can prevent my clients from pasting into a CLEditor textearea? Thanks!

Oh, by the way, I'm using jquery 3.2.1, so the "bind" command won't work -- it's been deprecated in favor of "on".
