Help with switches in GUI

I'm trying to create a GUI that has an on-off switch and a Pause button, however I am new to GUI and whenever I press the button I have the same callback displayed on both.... can anyone let me know what I need to change to make this work correctly??

Thanks

function Test_Button(hObject, eventdata, onOffHandle, varargin)
  %Create the GUI
  fig = figure;

    %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
    % Create a pushbutton for On/Off Button
    % Initial String is 'Off'
    onOff = uicontrol(fig,'Style','pushbutton',...
                          'String','Off',...
                          'Position',[460 330 70 50],...
                          'Callback',@onOff_Callback);
    % Create a pushbutton for Pause button
    % Initial String is 'Pause'
    pause = uicontrol(fig,'Style','pushbutton',...
                          'String','Pause',...
                          'Position',[460 280 70 50],...
                          'Callback',@pause_Callback);
    %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

    % Create the handles for onOff button
    onOffHandle = guihandles(fig);
    onOffHandle.strings = {'On';'Off'};
    guidata(fig, onOffHandle);

    % Create the handles for Pause button
    pauseHandle = guihandles(fig);
    pauseHandle.strings = {'Pause';'Paused'};
    guidata(fig, pauseHandle);

    %%Function for onOff button
    function varargout = onOff_Callback(a, eventdata)
    onOffHandle = guidata(a);
    % Get the current string
    str = get(a,'String');
    % See which string the current string matches with
    ind = find(strcmp(str,onOffHandle.strings));
    % Switch to the other string
    if ind == 1
          set(a,'String',onOffHandle.strings{2});
    else
          set(a,'String',onOffHandle.strings{1});
    end

    %%Function for pause button
    function varargout = pause_Callback(b, eventdata)
    pauseHandle = guidata(b);
    % Get the current string
    st = get(b,'String');
    % See which string the current string matches with
    ind = find(strcmp(st,pauseHandle.strings));
    % Switch to the other string
    if ind == 1
          set(b,'String',pauseHandle.strings{2});
    else
          set(b,'String',pauseHandle.strings{1});
    end

I think you are confused on how to add values to the guidata as now you are overwriting the values of OnOff by the pause values. Just use the debugging tool in matlab to step through your code line by line to see what is happening to your variables, especially starting from the onOffHandle

that said, you can check this with this code which should do what you want:

function Test_Button(hObject, eventdata, onOffHandle, varargin)
%Create the GUI
fig = figure;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Create a pushbutton for On/Off Button
% Initial String is 'Off'
onOff = uicontrol(fig,'Style','pushbutton',...
    'String','Off',...
    'Position',[460 330 70 50],...
    'Callback',@onOff_Callback);
% Create a pushbutton for Pause button
% Initial String is 'Pause'
pause = uicontrol(fig,'Style','pushbutton',...
    'String','Pause',...
    'Position',[460 280 70 50],...
    'Callback',@pause_Callback);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Create the handles for onOff button and Pause button
guiHandleData = guihandles(fig);
guiHandleData.stringsOnOff = {'On';'Off'};
guiHandleData.stringsPause = {'Pause';'Paused'};

guidata(fig, guiHandleData);

%%Function for onOff button
    function varargout = onOff_Callback(a, eventdata)
        % Get the current string
        str = get(a,'String');
        % See which string the current string matches with
        ind = find(strcmp(str,guiHandleData.stringsOnOff));
        % Switch to the other string
        if ind == 1
            set(a,'String',guiHandleData.stringsOnOff{2});
        else
            set(a,'String',guiHandleData.stringsOnOff{1});
        end
    end

%%Function for pause button
    function varargout = pause_Callback(b, eventdata)
        % Get the current string
        st = get(b,'String');
        % See which string the current string matches with
        ind = find(strcmp(st,guiHandleData.stringsPause));
        % Switch to the other string
        if ind == 1
            set(b,'String',guiHandleData.stringsPause{2});
        else
            set(b,'String',guiHandleData.stringsPause{1});
        end
    end
end
