My function does not execute to the end but i have no errors!!

When i call this function, it's called correctly but it's not executed to the end. I have no errors in Matlab.

function output_txt = GraphCursorCall(obj, event_obj, Nodes)
% Display data cursor position in a data tip
% obj          Currently not used
% event_obj    Handle to event object
% output_txt   Data tip text, returned as a character vector or a cell array of character vectors

h = event_obj.Target;
pos = event_obj.Position;
ind = find(h.XData == pos(1) & h.YData == pos(2), 1); %until here, EXECUTED

output_txt = {['Node ', num2str(ind)], ['OUTD: ', num2str(Nodes.OUT(ind))], ['IND: ', num2str(Nodes.IN(ind))]}; %NOT EXECUTED

disp("FINE"); %NOT EXECUTED
end

This time I edited your question for you. Next time, please use the tools explained on this page to make your question more readable.

Have you tried putting a break point at the first line of code of this function to see if it runs in the first place?
