What event allows you to track the complete loading of the AngulaJS component?

Question

Angular

Good afternoon!

const rootModule = angular
    .module('app.rootSchedule', [
        uiRouter,
        mainFilter.name
    ])
    .component('app.rootSchedule', {
        template,
        controller: rootScheduleController
    })

class rootScheduleController {
    constructor(dataService, $uibModal, $compile, $window, $http, storageService, $settings, $stateParams, $scope) {
          this.mainFilter = null;

In the rootScheduleController controller class, I need to track whether my mainFilter component has loaded, which is represented in html by the directive

<main-filter  on-change="$ctrl.filterChange(value)"></main-filter>
