Trying to add callback function in class

I am attempting to create a class the will have two line ROI objects. This class should have a callback function for when the lines are moved by the user. I am able to add a listener to the lines but only if the callback function is static.
Is it possible to do this without using a static method? Ultimatly I would like to use the callback method to compare the positions of the two lines as one of them is moved.
classdef imageRange < handle

properties
region double
line1
line2
rect
X double
end

methods
function obj = imageRange(axes, dataAxes)
x = dataAxes{1,4};
y = dataAxes{2,4};
midpoint = mean([x(1),x(3)]);

obj.X = floor(midpoint);

obj.rect = rectangle(axes,’Position’,[obj.X,y(1),…
ceil(midpoint)-floor(midpoint), y(3) – y(1)]);
obj.rect.EdgeColor = [0,0,0,0];
obj.rect.FaceColor = [.5,.5,.5];
obj.rect.FaceAlpha = .1;

obj.line1 = drawline(axes,’Position’,[floor(midpoint), y(1); …
floor(midpoint), y(3)],’Color’,[0.6350 0.0780 0.1840], …
‘InteractionsAllowed’,’translate’, …
‘MarkerSize’,.1, …
‘LineWidth’,1);

addlistener(obj.line1, ‘MovingROI’, @(src,event)obj.allevents(src,event));

obj.line2 = drawline(axes,’Position’,[ceil(midpoint), y(1); …
ceil(midpoint), y(3)],’Color’,[0 0.4470 0.7410], …
‘InteractionsAllowed’,’translate’, …
‘MarkerSize’,.1, …

obj.region = dataAxes{1,5};
end
end

methods (Static)
