Execute Macro

Hi - I am currently working on creating scenes. I am using the Java Script Module to execute macro as follow: After 10am, release the button to executed the associated macro. The macro contains : show popup and execute command through KNX server. My script works for the "show popup" but not for the KNX command. Can someone help? Thank you.

Note: below is a copy of the script:

IR.AddListener(IR.EVENT_START, 0, function()

{
var hour = IR.GetVariable("System.Time.Hour");
if (hour > 10)
{
IR.GetItem("Page 1").GetItem("Button").StartActions(IR.EVENT_ITEM_RELEASE);
};
