Nativescript (typescript) How do I access/get the instance/reference of a component from a different component?

Question

I am trying to access the component(Class instance) of NavigationButton and SearchBar in ActionBar from the component(Class instance) of a tabItem in a TabView. How do I do this?

<ActionBar color="black" title="">
    <NavigationButton #navBtn text="Go Back" android.systemIcon="ic_menu_back" (tap)="goBack()" [visibility]="navBtnVisibility"></NavigationButton>
    <StackLayout *ngIf="tabIndex == 0" titleView orientation="horizontal">
        <SearchBar hint="Search hint" [text]="searchPhrase" (textChange)="onTextChanged($event)" (submit)="onSubmit($event)" 
        color="black" textFieldHintColor="black"></SearchBar>
    </StackLayout>
</ActionBar>

<TabView #tabView [selectedIndex]="tabIndex" (selectedIndexChanged)="tabViewIndexChange(tabView.selectedIndex)">
    <StackLayout *tabItem="{title: 'Search'}" class="tab-item">
        <search-tab>
        </search-tab>
    </StackLayout>
    <StackLayout *tabItem="{title: 'Home'}" class="tab-item">
        <home-tab>
        </home-tab>
    </StackLayout>
    <StackLayout *tabItem="{title: 'Profile'}" class="tab-item">
        <!--<profile></profile>-->
        <profile-tab>
        </profile-tab>
    </StackLayout>
</TabView>

One Possible way to accomplish this is to use a service, bind your references from the Parent Component, and then in your child components you should inject the service.
