Are Components Reactive?

The data results isn’t updating when using a reactive helper. Should this update the results reactively OR do i need to add a config option OR is this not supported?

/index.js

Template.templateName.onRendered(function() {
    this.autorun(function() {
            reactiveIndex.set(someIndex);
    }
})
Template.templateName.helpers({
currentIndex() {
    return reactiveIndex.get();
}
});

/index.html

{{#EasySearch.Each index=currentIndex}}
    <li>{{this}}</lI>
{{/EasySearch.Each}}

onCreated() {

        this.autorun(function() { // added autorun
            let index = this.getData().index,
                indexes = [index];
            ...
        } // added autorun
}

options = dict.get('searchOptions') || {}, //added || {}
