Forcing an on change event event to fire

I am setting a number of attributes using setAttrs in the sheet:opened event, these attributes are used to calculate other attributes using on change events.   Sometimes the on change events for the attributes I set in the sheet:opened event are fired and sometimes there are not. Is there a way of forcing an event to fire.  I have quiet set to false in setAttrs.

Instead of forcing the event to fire, why don't you run the corresponding function directly?

It is ok I was making things complicated. I was being lazy the code is not supposed to go in the on:opened, I just placed in there to test it.  I moved it to an on:change for a checkbox and it works fine.  Thanks for the help.
