Can not save an updated uitable with editable column

I am using 2019b and I have an App Designer uitable with editable column. While I change a value it changes on the screen/GUI but not when I save it via a button. How can I solve it?

function saveDataButtonPushed(app, event)
    global myData;
    filter = {'*.csv'};
    [file, path] = uiputfile(filter);
    fullFileName = [path file];
    writecell(myData,fullFileName,'Delimiter',';')
end

I am not sure why you are defining a global variable. In App designer, you should directly use the properties of the app object to access data of uitable. See the attached file for an example of how to save csv file from uitable.
