javascript - How to only show few characters when pasting text in editor?

Question

trying to paste characters and if it is more than 50 characters ONLY show the first 50 characters. Can anyone tell me what I'm missing?

Here's my code: LIVE DEMO

CKEDITOR.instances.foo.on('paste',function(event){

    alert('paste');
    var deleteKey = 46;
    var backspaceKey = 8;
    var keyCode = event.data.keyCode;
    if (keyCode === deleteKey || keyCode === backspaceKey)
        return true;
    else
    {
        var textLimit = 50;
        var str = CKEDITOR.instances.foo.getData();
        if (str.length >= textLimit)
        // Need to add code here to only show the first 50 characters
            return false;
    }
});
