OnClientModeChange event is not fired in Mobile RenderMode.

Steps to reproduce:
Run the following code in a mobile Chrome (or mobile emulation) and click the edit Pencil button that switches the edit modes:

        <script type="text/javascript">
            function OnClientModeChange(editor, args) {
                var mode = editor.get_mode();
                switch (mode) {
                    case 1:
                        alert("We are in Design mode");
                        //do something
                        break;
                    case 2:
                        alert("We are in Html mode");
                        //do something
                        break;
                    case 4:
                        alert("We are in Preview mode");
                        //do something
                        break;
                }
            }
        </script>
