GUI Plot won't update inside 'MousePressedCallback' function

This is my current code. MyCellSelectionCallback gets the current selected row(s) of my uitable successfully. However, I would like to update a plot in my gui whenever this callback is executed and store the rows value to the handles structure. I can't figure out how to update my handles structure from inside this generated function. Currently I am able to reset "handles.PLOT" but my axes in my gui will not update and I am unable to retrieve "handles.Rows". Please help.

-----------------Table Update-------------------------

set(handles.uitable,'ColumnWidth',{125 125 125 125 126},'Units','normalized');
jUIScrollPane=findjobj(handles.uitable);
jtable=jUIScrollPane.getViewport.getView;

jtable.setNonContiguousCellSelection(false);
 jtable.setColumnSelectionAllowed(false);
 jtable.setRowSelectionAllowed(true);
 jtable = handle(jtable, 'CallbackProperties');
 set(jtable, 'MousePressedCallback',{@MyCellSelectionCallback,gcf});

%-----------------CallBack----------------------

function MyCellSelectionCallback(hObject, eventdata, currFig)

handles=guidata(currFig);
%handles=guidata(hObject);

rows=hObject.getSelectedRows+1;

Speed=table2array(handles.results.Value{rows,1}(:,3))';

idx1=Speed<=10;
idx2=Speed<=20 & Speed>10; 
idx3=Speed<=30 & Speed>20;
idx4=Speed>30;

c(idx1)=.1;
c(idx2)=.3;
c(idx3)=.5;
c(idx4)=.7;

cla(handles.PLOT);
set(handles.PLOT,'xtick',[]);
set(handles.PLOT,'ytick',[]);

axes(handles.PLOT)
hold on

NewPlot=color_line(LATITUDE,LONGITUDE,c);

handles.Rows=rows;

% Update handles structure
guidata(currFig);

%-------------Edit----------------

I was able to update the handles by adding this line to the end of the callback.

guidata(currFig,handles);

However, I am still unable to display my new plot to my gui axes. Currently it will only reset but not display.

Any suggestions?
