How can I activate (bring into focus) Illustrator after pressing a Palette button in my AIScript

/*I can already use this illustrator script. My problem is that after the button works, the window title remains active. 
    After the button does its job, the window title should remain passive and focus on the illustrator page. I tried very hard but I couldn't succeed.*/
