You shouldn't run jquery/other plugins outside angular/angular2 rendering pipeline. Possible solutions are:

use existing angualr2 component libraries (https://valor-software.com/ng2-bootstrap/#datepicker, http://www.primefaces.org/primeng/, or any vendor's plugins)

create your own component, something similar to:

import { Component, Input, Output, OnInit, AfterViewInit, OnDestroy } from '@angular/core';
import { ViewChild, EventEmitter, ElementRef } from '@angular/core';
@Component({
   selector: 'date-time-picker',
   template: '<input #input type="text" class="form-control" />' 
})
export class DatetimePickerComponent implements AfterViewInit {
   @ViewChild('input') input:ElementRef;
   ngAfterViewInit() { //only here you are sure that html is available.
       $(this.input.nativeElement).datepicker({
          format: 'mm/dd/yyyy',
          container: container,
          todayHighlight: true,
          autoclose: true 
       });
   }
}

and use it everywhere in your app:

<date-time-picker />

maybe you are also interested in EventEmitter, to catch changes of the selected value.

if needed: this is the full code of directive I wrote to use http://eonasdan.github.io/bootstrap-datetimepicker/ and two way data binding in angular2 app:

    import { Component, Input, Output, OnInit, AfterViewInit, OnDestroy } from '@angular/core';
    import { ViewChild, EventEmitter, ElementRef } from '@angular/core';
    import { ControlValueAccessor, NgControl } from '@angular/common';
    import * as moment from 'moment';

    declare var $: JQueryStatic;

    //http://eonasdan.github.io/bootstrap-datetimepicker/

    @Component({
        //moduleId: module.id,
        selector: 'date-time-picker',
        template: '<input #input type="text" class="form-control" />'
    })
    export class DatetimePickerComponent implements ControlValueAccessor, OnInit, AfterViewInit, OnDestroy {

        @Input('view-mode') viewMode: string;
        @Input('view-format') viewFormat: string;

        @Input('ngModel') ngModel:Date;
        @Output('ngModelChanged') ngModelChanged:EventEmitter<Date>;

        private ngModelChangeCallback:(Date)=>void;
        private ngModelTouchedCallback:Function;

        private jqueryObject: any;

        @ViewChild('input') input:ElementRef;

        constructor(private ctrl: NgControl) { 
            this.ctrl.valueAccessor = this;
            this.ngModelChanged = new EventEmitter<Date>();
        }

        ngAfterViewInit() { 
            let jElement:any =  $(this.input.nativeElement);

            this.jqueryObject = jElement.datetimepicker({
                viewMode: this.viewMode,
                format: this.viewFormat,
                defaultDate: this.ngModel
            });

            this.jqueryObject.on("dp.change", (e:any) => {
                //this.ngModelChange.emit(e.date.toDate());
                this.ngModelChangeCallback(e.date);
                this.ngModelChanged.emit(e.date);
            });
            this.jqueryObject.on("dp.show", (e:any) => {
                this.ngModelTouchedCallback(e.date);
            });

        }

        ngOnInit() {

        }

        ngOnDestroy() {
            if(this.jqueryObject) {
                $(this.jqueryObject).data("DateTimePicker").destroy();
            }
        }

        writeValue(date:Date) {
            if(!this.ngModel && !date) //no changes
                return;

            if(!moment(this.ngModel).isSame(date)) {
                this.ngModel = date; 

                if(this.jqueryObject) {
                    $(this.jqueryObject).data("DateTimePicker").date(this.ngModel);
                }
            }
        }

        registerOnChange(fn: (Date)=>void) {
            this.ngModelChangeCallback = fn;
        }

        registerOnTouched(fn: Function){
            this.ngModelTouchedCallback=fn;
        }
    }

to use in other components as:

  <date-time-picker [(ngModel)]="selectedDate" (ngModelChanged)="selectedMonthChanged($event)" view-mode='years' view-format='MM/YYYY'></date-time-picker>

thanks for your reply.but is shows an error , "Class 'DatePickerComponent' incorrectly implements interface 'On Destroy'. Property 'ngOnDestroy' is missing in type 'DatePickeComponent'. — byogesh, Jun 06 '16 at 11:55
I've edited it removed interfaces not implemented + added full code of the directive. I don't know if I've followed the best practices, happy to receive suggestions. — Sierrodc, Jun 06 '16 at 12:15

I believe that you need a new entry point to your JS code when using Angular 2.

See Angular2 equivalent of $document.ready()

I don't think that you can easily just run your Bootstrap/Jquery code in Angular2 without porting stuff. Are you using https://valor-software.com/ng2-bootstrap/ ?
