If you've just recently upgraded from Redactor v9 to v10, you will find that the above code does not work since Redactor has now updated most of its existing APIs and added new modules. For example, .modalInit(), .selectionRestore(), .selectionSave(), .insertHtml() from v9 is now .modal.load(), selection.restore(), .selection.save(), etc in v10.

I've modified the above code slightly and am adding it here if anybody's interested. Feel free to edit/ optimize it if needed.

if (!RedactorPlugins) var RedactorPlugins = {};

RedactorPlugins.pasteasplaintext = function()

            this.button.addCallback(button, this.pasteasplaintext.showMyModal);
        },
