将复选框添加到复选框组->侦听器

Question

I have a checkbox group to which I now add checkboxes at runtime. The problem is my change listener, which is defined on the checkboxgroup. It is not fired when the new checkboxes are checked - but it is when the old ones are. (Furthermore, it is not fired when new checkboxes are added - although the new checkboxes are created checked:true )

So I want to add the change listener, which is defined on the checkboxgroup in variable me , to all child checkboxes. I think this has to be the way Ext does it, right?

newItems.push(Ext.create('Ext.form.field.Checkbox',Ext.applyIf(Ext.clone(me.defaults),{
    boxLabel : someString,
    name : someString,
    inputValue : someString,
    checked : true,
    listeners : {
        change: me.on('change');
    }
})));

But I am unsure how to achieve my goal (in the third-to-last-line), that the change event for the checkboxgroup is fired whenever the change event is fired for the checkbox.

Answer 1

I found the answer:

change:function() { me.fireEvent('change'); }

would fire the change event on the checkbox group whenever the change event on the checkbox is triggered.
