Here is my full implementation of modal bootstrap angular2 component:

I assume that in your main index.html file (with and tags) at the bottom of tag you have:

modal.component.ts:

import { Component, Input, Output, ElementRef, EventEmitter, AfterViewInit } from '@angular/core';

declare var $: any;// this is very importnant (to work this line: this.modalEl.modal('show')) - don't do this (becouse this owerride jQuery which was changed by bootstrap, included in main html-body template): let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');

@Component({
  selector: 'modal',
  templateUrl: './modal.html',
})
export class Modal implements AfterViewInit {

    @Input() title:string;
    @Input() showClose:boolean = true;
    @Output() onClose: EventEmitter = new EventEmitter();

    modalEl = null;
    id: string = uniqueId('modal_');

    constructor(private _rootNode: ElementRef) {}

    open() {
        this.modalEl.modal('show');
    }

    close() {
        this.modalEl.modal('hide');
    }

    closeInternal() { // close modal when click on times button in up-right corner
        this.onClose.next(null); // emit event
        this.close();
    }

    ngAfterViewInit() {
        this.modalEl = $(this._rootNode.nativeElement).find('div.modal');
    }

    has(selector) {
        return $(this._rootNode.nativeElement).find(selector).length;
    }
}

let modal_id: number = 0;
export function uniqueId(prefix: string): string {
    return prefix + ++modal_id;
}

modal.html:

    

        

            

                ×Close
                
                
{{ title }}
            
            

                
            

            

                
            
        
    

And example of usage in client Editor component: client-edit-component.ts:

import { Component } from '@angular/core';
import { ClientService } from './client.service';
import { Modal } from '../common';

@Component({
  selector: 'client-edit',
  directives: [ Modal ],
  templateUrl: './client-edit.html',
  providers: [ ClientService ]
})
export class ClientEdit {

    _modal = null;

    constructor(private _ClientService: ClientService) {}

    bindModal(modal) {this._modal=modal;}

    open(client) {
        this._modal.open();
        console.log({client});
    }

    close() {
        this._modal.close();
    }

}

client-edit.html:

{{ bindModal(editModal) }}
    Som non-standart title
    Some contents
    Close

Ofcourse title, showClose, mhead and mfoot ar optional parameters.
