Should share some actual code and not just image.

You didn’t declare isOn, so showNow won’t affect it…

```auto
var isOn = Observable(false);
function showNow() {
  isOn.value = true;
}
module.exports = {
  isOn: isOn
};

```

my bad, forgot to export the “showNow” function:

```auto
var isOn = Observable(false);
function showNow() {
  isOn.value = true;
}
module.exports = {
  isOn: isOn,
showNow: showNow
};

```
