Actually my problem could not be hacked the way presented above:

- yes, the notification level was mutated but…
- it was not saved. One would need to click elsewhere to save it with an other action.

By intensely searching random keywords on the github code database, I could find some structure like this one:  
`{{d-button action=(action "up" wc) ...}}`.

With some testing, I came to the conclusion it works this way:

- template:

```hbs
{{d-button action=(action "nameoftheaction" arg1 arg2) ...}}`.

```

- JS:

```js
api.modifyClass("component:some-component", {
    actions: {
        nameoftheaction(arg1, arg2, argA, argB) {
            console.log(arg1);
            console.log(arg2);
            console.log(argA);
            console.log(argB);
        }
    }
})

```

The first arguments `arg1`, `arg2` of the methods are the one given by the template. The remaining arguments `argA`, `argB`… may be given by the specificity of the component (for exemple, the `category-notifications-button` will return an integer depending on the setting the user clicks on).

I am absolutely not sure what I write is correct but it may help someone asking the same question I did.
