Set dialog field value as selected text

Question

I want to code CKEditor plugin. I have added button on panel and when I press it dialog is shown. In this dialog I can set text and after OK pressed this text inserted to the editor.

But I want add functionality. When I select text in editor and press this button I want see selected text in that dialog field. And after editing and press Ok selected text must be replaced with new one.

Thanks!

This is not 100% working, the first part is working, the final replacement isn't..

CKEDITOR.plugins.add( 'example',
{
    init: function( editor )
    {
        editor.addCommand( 'exampleDialog', new CKEDITOR.dialogCommand( 'exampleDialog' ) );

        editor.ui.addButton( 'example',
        {
            label: 'Insert a Link',
            command: 'exampleDialog'//,
            //icon: this.path + 'images/icon.png'
        } );

        CKEDITOR.dialog.add( 'exampleDialog', function( editor )
        {
            return {
                title : 'example Properties',
                minWidth : 400,
                minHeight : 200,
                contents :
                [
                    {
                        id : 'general',
                        label : 'Settings',
                        elements :
                        [
                            {
                                type : 'text',
                                id : 'mystring',
                                label : 'text',                             
                                commit : function( data )
                                {
                                    data.text = this.getValue();
                                }
                            }
                        ]
                    }
                ],

                onShow : function() {
                    //this._ranges = editor.getSelection().getRanges()
                    var mySelection = editor.getSelection().getSelectedText();
                    this.setValueOf("general","mystring",mySelection);

                },

                onOk : function()
                {
                    var data = {};
                    this.commitContent( data );
                    var txt = data.text;


                    editor.insertText(txt);  //this is not correct, since selection is being cleared...
                }
            };
        });
    }
});
