In Titanium how do I execute a button click event from code?

I t开发者_开发百科ried

btn.click();

And the error message is 'Cannot call property click in object ti.modules.titanium.ui.ButtonProxy@44f61. It is not a function, it is "object"'

---

btn.fireEvent('click');

this should work

---

btn.addEventListener('click',function() {
    Titanium.API.info('Button Clicked');

});
