Callback issue with uiMenu

Having some issues with callback using uimenu, when a certain option is selected I want it to change the color map of the whole figure. Here is my code.

Function Startup 

fig = figure('Toolbar','none','MenuBar','none')
Main = uimenu(fig,'Label','File'); 
ImageSettings = uimenu(File,'Label','Jet',...
               'Callback', 'CM1');
end 

function CM1

%colormap(jet)
disp('Jet')
end

The error that occurs is

Too many input arguments.

   Also I have tried to change my callback from: 'Callback', 'CM1'); to 
'Callback', @CM1);

That did not seem to work either.

The function CM1 requires 2 input arguments as all callbacks:

function CM1(ObjectHandle, EventData)

You do not have to use the values, but they must exist.

Another idea would be an anomyous function to crop the inputs:

'Callback', @(x,y) CM1

But this looks more confusing, in my opinion.

I get a really weird error when I do that saying:

Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N) to change the limit. Be aware that exceeding your available stack space can crash MATLAB and/or your computer.
