Bootstrap modal not working with this template

[topex-psy]

I use a simple bootstrap modal from bootstrap 4.0 documentation, when I show the modal, modal is not visible and transparent layer will prevent me to click anywhere on the page.

This is the code of my modal:

<div class="modal fade" id="modal_komplain" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
	<div class="modal-dialog" role="document">
		<div class="modal-content">
			<div class="modal-header">
				<h5 class="modal-title" id="exampleModalLabel">Komplain</h5>
				<button type="button" class="close" data-dismiss="modal" aria-label="Close">
					<span aria-hidden="true">&times;</span>
				</button>
			</div>
			<div class="modal-body">
				<div class="text-center"><?=dom_img_spinner?></div>
			</div>
			<div class="modal-footer">
				<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
				<button type="button" class="btn btn-primary">Save changes</button>
			</div>
		</div>
	</div>
</div>

Please share the HTML code of the element which triggers the modal.

I just use $('#modal_komplain').modal('show');

[fathimalinsak]

please add the attributes data-toggle="modal" data-target="#modal_komplain" to the trggering element and remove the triggering through script.

Please refer http://getbootstrap.com/docs/4.1/components/modal/#live-demo for more details.

I also have this problem with modal, I am used to open them from codebehind using an hidden button and a small piece of jscript, like this:

<button type="button" style="display: none;" id="btnModal" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#modalRegole">Launch demo modal</button>

<script type="text/javascript">
        function ShowModal() {
            $("#btnModal").click();
        }
    </script>

and this code behind call: ClientScript.RegisterStartupScript(Me.GetType(), "alert", "ShowModal();", True)

This works on all my other bootstrap project except the one where i'm using sb admin template.
I need to edit what the modal will show by changing its components texts and visibility and I don't know how to do this without using code behind. So I don't want to open them using attributes data-toggle and data-target
