Personas 3.0: .setTimeout(): The time interval does not show impact.

Hi Personas experts,

I am trying some UI events that can be triggered by the timeout function. But it seems that the timeout intervel does not effect. My JS look like this:

      setTimeout(myEventHandler(),3000);  //I expect the event handler func to be called after 3 secs.

and

      window.setTimeout(myEventHandler(), 3000);

It seems that no matter which value I used, the handler function is called in the same time interval.

Does anyone have idea why the time interval 3000 does not have impact?

Thanks.

Dong
