how to have ember 3.4 component properties combining 'computed' and 'on()'

We have code in our ember 2.9.0 project which has Components with properties like this:

hide: on("init", computed("hasEnoughData", function () {
    return !this.hasEnoughData;
})),

When I migrate it to ember 3.4, it breaks with this error:

Assertion Failed: on expects function as last argument

Basically, the on() function expects the last param to be a function. This code used to work with 2.9 to combine both computed and on().

Is there a recommended way to do this with ember 3.4?
