It looks like you have already defined a callback function for when the value of the text area is changed. Have you added any code to it? Without seeng the code in the callback function, as well as knowing what it is you expect to happen, it's really difficult to provide specific feedback.

If you want the callback to execute when you are changing the value programmatically, you just need to call that function inside the callback function that is executing.
% Button pushed function: Button
function ButtonPushed(app, event)
[file,path] = uiputfile ({'*.*'}, 'Select a file');
[~,name,~] = fileparts(file);
app.TextArea.Value=name;
TextAreaValueChanged(app, app.TextArea)
end
