[Solved] How to use virtual-dom's "h" helper in <head> for header-dropdown hamburger widget override? + How to override @computed method?

I’m not sure if this is the only way to do it, but I’ve modified computed properties in customizations like this (the example is using the availableSorts computed property):

 api.modifyClass('component:edit-category-settings', {
    availableSorts: Ember.computed(function() {
    let sorts = this._super();
    let voteSort = {};
    voteSort["name"] = "Votes";
    voteSort["value"] = "votes";
    sorts.push(voteSort);
    return sorts;
    })
  });
