Breaking a loop GUI?

Reading in accelerometer data in a GUI code. I'm trying to break the loop while reading by using the following code...
function pushbutton8_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton8 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
a = getappdata(handles.text11, 'text11');
%COMPORT
comPort = '/dev/tty.usbmodemfd121';
%READS SERIAL
[accelerometer.s,serialFlag] = setupSerial(comPort);
calCo = calibrate(accelerometer.s);
%READS DATA
while (a == 0)
if (a == 1)
closeSerial
end
[gx gy gz] = readAcc(accelerometer,calCo);
cla;
r = sqrt((gx^2)+(gy^2)+(gz^2));
r
end
guidata(hObject, handles);
My problem is that the data keeps reading even when (a == 1), which is activated from a separate pushbutton. I've already tested the outputs of both each pushbuttons and they do read 0 and 1, but when reading the data, if I press the 1 pushbutton the data will still read.

@Amed: Neither "oh ok" nor "anything" contains enough information to understand, if this answer has solved your problem or not. If you want help, provide more details instead of bumping the thread without new informations.
