cla reset stops UIAxesButtonDown from working

Hello. I have a UIAxes that I plot on and I want to manually be able to add text where ever I click on the graph. I am using the following to do this UIAxesButtonDown(app, event) defined as:

ax=app.UIAxes;              
%set(ax, 'hittest', 'off');
cursorPos = ax.CurrentPoint(1,1:2);
app.curX=(cursorPos(1));                   % Current Mouse Coords defined as a public property
app.curY=(cursorPos(2));                   % Current Mouse Coords defined as a public property

Cla(ax,’reset’)

ax=app.UIAxes;
b=ax.Children
n=numel(b)
for i=1:n
    delete(b(i))             
end

function  myAddText(app)             
ax=app.UIAxes; 
x=app.curX;% SavedMouse Coords
y=app.curY; % SavedMouse Coords           
txt=app.AddTitleEditField.Value;
txt=horzcat('\leftarrow',txt);
text(ax,x,y,txt,'Color',cl,'FontSize',12,'Interpreter', 'tex','HorizontalAlignment','left','VerticalAlignment','middle');
