Joomla 3: display view with toolbar in modal

Question

I'm developing an MVC component for Joomla 3.x with currently 3 views:

VIEWS
|-PAGES (displays all pages in a list, ordinary joomla view) 
  |-view.html.php
  |-TMPL
    |-default.php
|-PAGE (forms for page editing)
  |-view.html.php
  |-TMPL
    |-edit.php
|-ITEM (forms for item editing)
  |-view.html.php
  |-TMPL
    |-params.php

In my page.edit view, I wanna call my item.params view via a bootstrap modal. currently, I have this setup (working modal) (link in layout edit.php):

<a href="<?php echo JRoute::_('index.php?option=com_pages&view=item&layout=params&tmpl=component&id='.$elem->id); ?>" class="modal"><span class="icon icon-cog"></span></a>

with behavior.modal enabled.

EDIT: note &tmpl=component (administrator template disabled)

How can I e.g. display save buttons and get them working? (with JToolbar if possible?)

Are there possibly beter ways to accomplish this?

EDIT: I've tried @Dmitry-Rekun's answer and I'm glad to say it works! However I've run into some issues with the implementation... :(

Answer 1

You can display them like in the ordinary list view. See for example modal.php of the articles view. Just use JToolbarHelper to display buttons.

Or you can display buttons like in batch files:

<button class="btn btn-primary" type="submit" onclick="Joomla.submitbutton('article.batch');">

See batch of the articles view.
