When I use image control in listview, javascript doesn't work. How can I solve it?

<asp:ListView ID="ListView1" runat="server">
        <ItemTemplate>

        <div class="col-lg-3 col-md-6 col-sm-6">
                <div class="project-item">

                          <asp:Image ID="Image2" runat="server" ImageUrl='<%# Eval("gallery_img") %>' Style="cursor: pointer" onclick="return false LoadDiv(this.src, this);" />

                </div><!--project-item end-->
        </div>
       </ItemTemplate>
</asp:ListView>

<pre><pre><pre>I made a photo gallery. When I run it with datalist, it works fine. When the photo is clicked, a popup opens. But since it is not a responsive layout, I preferred to use Listview. But this time the popup does not open. Is there something triggering in the background, javascript code or onclick doesn't kick in.
