timer in livecycle

Hi everybody

I try to get the presence of these objects when the file is opened. I use the initialize event. It works in a random way. Sometimes it's OK, sometimes it stops anywhere and sometimes it doesn't start. I assume that a pause is needed. But how can I do that.

Many thanks for your help !

var Test = app.setTimeOut('xfa.resolveNode("xfa.form.ira.Page1.help_number.one").presence = "visible";', 500); 

var Test = app.setTimeOut('xfa.resolveNode("xfa.form.ira.Page1.help_number.two").presence = "visible";', 1000); 

var Test = app.setTimeOut('xfa.resolveNode("xfa.form.ira.Page1.help_number.three").presence = "visible";', 1500);
