I want to execute the function moverIntXx within the button and nothing happen. If I execute the function outside the button, the function runs fine. What is that I don’ t understand? Thanks.

SetAttributes[moverIntXx,HoldFirst];
moverIntXx[var_,n_]:=Module[{t},
t=Flatten[Table[{1,2,3},{i,1,n}]];
Map[(Pause[0.05];FinishDynamic[];var=#)&,t];
];
Dynamic[var]
Button[
	Style[Tooltip["Clic"], Red,FontFamily->"Palatino",18],
	moverIntXx[var,6],Appearance->"Frameless"]

Adding option Method → “Queued” to the button helps.
