A static text does not update after set() until the callback has finished

I am developing an interface.
In each loading time, I have a status information to notify the user when the information is ready.
function acceptButton_Callback(hObject, eventdata, handles)
set(handles.statusTag,'String','Status: Loading...');
% More code to retrieve values from another handles elements
% This function lasts to return a value from 5-10 seconds
output = UserRequirements(filepath, index_selected, timeValue, softnessValue, geoErrorValue);
% Here I fill a listbox with output and lasts from 5 to 10 seconds
set(handles.statusTag, 'String', 'Status: Ok');
guidata(hObject, handles);
The normal funcionality is to see how that text change from Status: Ok to Status: Loading... and after 5-10 seconds, change from Status: Loading... to Status: Ok.
Well, if I run this code in debug mode, I can see the change. If not, seems that the text changing happen after all code execution has finished.
I have done the same in another function and everything works ok, but here not.
Any suggestions?

Hi,
It looks like the call to change the status text is taking time to update the graphics. You may want to use the function "drawnow" to resolve this issue. For more details regarding "drawnow" function, please refer to the link below:
