How do I plot values on top of bar?

the following is my code. I want to put values on top of the bars but I could not solve the problem. I have gone through the previous but could not figure out the exact positioning.

x = [20	40 60 80 100];
y = [0.0036 0.0149;0.0033 0.0149;0.0023 0.0192;0.0021 0.0235;0.0018 0.0279];
bar(x,y)
a = (1:size(y,1)).';
x_check = [a-0.25 a+0.25];
for k=1:size(y,1)
    for m = 1:size(y,2)
        text(x_check(k,m),y(k,m),num2str(y(k,m),'%0.2f'),...
            'HorizontalAlignment','center',...
            'VerticalAlignment','bottom')
    end
end

x = [20	40 60 80 100]';
y = [0.0036 0.0149;0.0033 0.0149;0.0023 0.0192;0.0021 0.0235;0.0018 0.0279];
bar(x,y)

text(x, y(:,1), num2str(y(:,1)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom')
text(x, y(:,2), num2str(y(:,1)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom')

Thank you very much. It almost works but the alignment does not work. Can you have a look.

Check the properties of text, you can try chaning the allignment which suits you.
