Getting hold of original event within ifChanged function

[seagullmouse]

My set up

• I have a table where each row has a checkbox (lets call them C1, C2, ... Cn)
• At the top of the table I have a check/uncheck all checkbox (Ca)
• When I check Ca I use the ifChanged-Ca event to check all the other checkboxes C1, C2, ... Cn.
• This causes the ifChanged-C1, ifChanged-C2, ifChanged-Cn events to fire
• Within this ifChanged-C1, ifChanged-C2, ifChanged-Cn events I want to have code that says something like,

function (event) {
if(triggered by checked/unchecked directly on Cn){
doA();
}
if(originally triggered by checkbox Ca){
doB();
}
}

• However I can't get hold of the original event within the event parameter. i.e. event.originalEvent is undefined.
• Any ideas how I can achieve the above?

Thanks in advance
