How to add both title and change the scale of a color bar

I am trying to add a title to the colorbar of a contour plot but also change the scaling of the colorbar. All I have found online is instructions for one or the other. When I have this:

title(colorbar, 'Electric Potential Field, V');
caxis([-45 150]);
set(colorbar, 'YTick', -45:15:150);

I get the scale I want but not the title. If I put the title command afterward I lose the scaling. Is there a command that I can use to have both?

cb=colorbar();
cb.Label.String = 'Electric Potential Field, V';
cb.Ticks = -45:15:150;
caxis([-45 150]);
