Post back stop working inside update panel control

After I load few JavaScript files inside a master page the post back is not working that is found inside an update panel. The post back works fine without the javascripts loaded.

    <script type="text/javascript" src="<%# Page.ResolveUrl("/popper/popper.min.js") %>"></script>
    <script type="text/javascript" src="<%# Page.ResolveUrl("/anchorjs/anchor.min.js") %>"></script>
    <script type="text/javascript" src="<%# Page.ResolveUrl("/is/is.min.js") %>"></script>
    <script type="text/javascript" src="<%# Page.ResolveUrl("/fontawesome/all.min.js") %>"></script>
    <script type="text/javascript" src="<%# Page.ResolveUrl("/lodash/lodash.min.js") %>"></script>
    <script type="text/javascript" src="<%# Page.ResolveUrl("/list.js/list.min.js") %>"></script>
    <script type="text/javascript" src="<%# Page.ResolveUrl("/assets/js/theme.js") %>"></script>```
