Use uglipop.js inside .net form

My code below is on a .aspx page.

The test1 button works fine as long as I place it outside the form tag
Button pops just fine

But it opens and closes when the button is placed inside the form tag... not really a problem because what I want to do is use a .net button inside the form tag

Then... on .Net button click
I run some code...
And execute the custom1(); from server side.

Here is all the code
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<!DOCTYPE html>
    <title>HTML, CSS and JavaScript demo</title>
    <script src=""></script>

        .put {
            border-radius: 10px;
            background-color: white;
            width: 300px;
            height: 300px;
            padding: 10px;
            -webkit-box-shadow: 0px 0px 39px 12px rgba(0,0,0,0.75);
            -moz-box-shadow: 0px 0px 39px 12px rgba(0,0,0,0.75);
            box-shadow: 0px 0px 39px 12px rgba(0,0,0,0.75);
    <!-- Start your code here -->
    <form id="form1" runat="server">

        <p class="lw">Hello Weaver!</p>
        <asp:Button ID="btnClick" runat="server" Text=".Net Buttone" OnClick="btnClick_Click" />

        <button class="button-blue" id="test1" runat="server" onclick="custom1();">Try it</button><br />
        <br />
        var custom1 = function () {
                class: 'put', //styling class for Modal
                source: 'html',
                content: '<div> All HTML goes here </div>'

Open in new window

    protected void btnClick_Click(object sender, EventArgs e)
      //some code... blah blah blah
     //execute the custom1(); here

Open in new window

And call the custom1(); script

I'm using the codes below to do that.

1. in your front end, add jQuery include in the <head> tag section:

<script type="text/javascript" src=""></script>

Open in new window

2. then your code behind:

protected void btnClick_Click(object sender, EventArgs e)
            ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "script", "$(document).ready(function () { custom1(); });", true);

Open in new window
