Modal opens but it's not fullscreen

[RezaRahmati]

Hey

I tried to use fullscreen-modal, modal opens but it's not full screen.

I am using it in Angular4 project, and this is how it's configured

in .angular-cli.json

                "../node_modules/jquery/dist/jquery.js",
                "../node_modules/bootstrap/dist/js/bootstrap.js",
                "../node_modules/bootstrap-modal-fullscreen/dist/bs-modal-fullscreen.js",

I checked script is included

Also when I call fullscreen method I get error, that it seems it can't find the method

This is my code inside component

  @ViewChild('itemModal') itemModal: any;

addItem() {
    this.itemModal.fullscreen();
  }

and this is my component

<div bsModal [config]="{ show: false, backdrop: 'static', keyboard: true }" #itemModal="bs-modal" class="modal fade modal-fullscreen" tabindex="-1"
    role="dialog" aria-hidden="true">
    <div class="modal-dialog modal-sm itemModal">
