Issues have been found with angular 2's (click) functionality when used on elements outside of its intended

I have encountered an issue with a basic component responsible for managing display classes on my data tables. It seems that the only way I can make it function properly is by having the data table load within the actual component itself. Strangely, when I attempt to use the buttons on data tables in other components, they do not respond. Despite importing the necessary class and including the directive, it appears that the functionality does not extend beyond its own nested scope.

import {Component} from 'angular2/core';
import {NgClass} from 'angular2/common';
import {DataTable} from '../../components/datatable/datatable';
import {TestDatatable} from "../../views/grids/testDatatable";
@Component({
    selector: 'show-parent',
    inputs: ['isDisabled'],
    directives: [NgClass, TestDatatable],
    template: `
        <i class="fa fa-sitemap" (click)="toggleOpen($event)"></i>
        <i class="fa fa-th-large" (click)="toggleSplitScreen($event)"></i>


 //The buttons work on this datatable below but if I move 
 //  this selector somewhere else it no longer works

        <myDatatable [ngClass]="{'panel-open': isOpen, 'panel-split':
        isSplit}" class="parent-grid"></myDatable>   
     `
})
export class ShowParent {
    isOpen = false;
    isSplit = false;

    toggleOpen(event) {
        event.preventDefault();
        this.isOpen = !this.isOpen;
    }

    toggleSplitScreen(event) {
        event.preventDefault();
        this.isSplit = !this.isSplit;
    }
}

Perhaps this method I'm sharing could help you achieve your goal. You can utilize DI for this purpose. More information can be found here.

import {SharedSer} from 'yourPath/sharedSer';
..//

bootstrap(AppComponent, [SharedSer]);

If you include [SharedSer] in the bootstrap, you will have access to the same instance throughout the application without needing to use providers: [SharedSer].

import {Injectable} from 'angular2/core';

@Injectable()
export class SharedSer {

    //This class allows for implementing functions like:
    //  get and set keywords that act as properties
    //  get and set methods/functions

    isOpen:  boolean = false;
    isSplit: boolean = false;

    constructor() {

    }
}

import {SharedSer} from 'yourPath/sharedSer';
..//

export class ShowParent {

    constructor(private service: SharedSer) {

    }  

    toggleOpen(event) {
        event.preventDefault();
        this.service.isOpen = !this.isOpen;
    }

    toggleSplitScreen(event) {
        event.preventDefault();
        this.service.isSplit = !this.service.isSplit;
    }
}

import {SharedSer} from 'yourPath/sharedSer';
..//

export class YourDatatable {

    constructor(private service: SharedSer) {

    }          
}

The issue lies in the fact that the isOpen and isSplit properties are not visible to other components.

To address this, you can access the isOpen and isSplit properties in another component.

One way to do this is by creating a shared service with isOpen and isSplit as properties. Simply import the service where needed and access these properties.

If only a parent component requires access, there are alternative methods such as using the ViewChild decorator or creating an event for the parent to listen to and set its own isOpen and isSplit properties accordingly.
