buttondown performs after zoom out

Hello, I wrote a GUI code where there are three axes with defined buttondownfcn. When I use zoom out tool each buttondownfcn is performed after zooming, so matlab evaluates zoom out tool as a mouse click. Is there any way to prevent performing buttondown function after zoom out? code:

function axes1_CreateFcn(hObject, eventdata, handles)
set(zoom_handle,'ActionPostCallback',{@clickpostcallback});

function axes2_CreateFcn(hObject, eventdata, handles)
set(zoom_handle,'ActionPostCallback',{@clickpostcallback});

function axes3_CreateFcn(hObject, eventdata, handles)
set(zoom_handle,'ActionPostCallback',{@clickpostcallback});

function clickpostcallback(obj,evd)
handles = guidata(obj);
ax = handles.axes;
linkaxes(ax,'xy');
