WACounter is displayed but doesn't increase/decrease

Question

I'm new to smalltalk/pharo/seaside and i get trouble using a simple WACounter. I created a component and added this:

wa := WACounter new.
html render: wa.

The counter is displayed in my localhost but doesn't increase/decrease on click. It must be silly but i can't find what's happend. thanks

You should make the counter an instance variable, eg

counter
    ^ counter

and

counter: aCounter
    counter := aCounter.

then, your #children should answer this counter, too:

children
    ^ Array with: self counter

In your rendering method, then just render the counter:

renderContentOn: html

    html render: self counter.
