RadAjaxManager not loading JavaScript Function

[Felix]

I'm having a weird occurrence when adding a RadAjaxManager to a Webform. From ButtonClick codebehind I am calling a java script function successfully, but fails when I add a RadAjaxManager.

CodeBehind:
    protected void btnUpload3DModel_Click(object sender, EventArgs e)
        {

            try
            {
                FileUpload fileUpload = FileUploadControl;

                string physicalFolder = Server.MapPath("~/assets/");
                if (fileUpload.HasFile)
                {
                    string uploadFile = physicalFolder + fileUpload.FileName;
                    fileUpload.SaveAs(uploadFile);

                    string testFile = "/assets/" + fileUpload.FileName;
   
                   ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "NovaCopyStlViewer('" + testFile + "')", true);
                }
            }
            catch (Exception)
            {

                throw;
            }

        }

Javascript function:

 <script type="text/javascript">
        function NovaCopyStlViewer(file)
        {

            var cv = document.getElementById('canvas_drop');
            cv.style.display = 'block';

            var e = document.getElementById('select_options');
            e.style.display = 'block';



            var mycanvas = document.getElementById('upload_canvas');
            var viewer = new JSC3D.Viewer(mycanvas);
            var theScene = new JSC3D.Scene;

            var stlpath = file;
            viewer.setParameter('SceneUrl', stlpath);
            viewer.setParameter('InitRotationX', 20);
            viewer.setParameter('InitRotationY', 20);
            viewer.setParameter('InitRotationZ', 0);
            viewer.init();
            viewer.update();
        }
    </script>



The error I am seeing after adding RadAjaxManager is as follows
JavaScript critical error at line 343, column 42 in http://localhost:32135/3DPrototypeQuote.aspx\n\nSCRIPT1004: Expected ';' 

Notice there is no SemiColon between NovaCopyStlViewer('/assets/Inverted.stl') and Sys.Application.add_init(function() 
This is where Visual Studio is showing the error. 

DOM:
<script type="text/javascript">
//<![CDATA[
NovaCopyStlViewer('/assets/Inverted.stl')Sys.Application.add_init(function() {
    $create(Telerik.Web.UI.RadAjaxManager, {"_updatePanels":"","ajaxSettings":[],"clientEvents":{OnRequestStart:"",OnResponseEnd:""},"defaultLoadingPanelID":"","enableAJAX":true,"enableHistory":false,"links":[],"styles":[],"uniqueID":"ctl00$ContentPlaceHolder1$RadAjaxManager1","updatePanelsRenderMode":0}, null, null, $get("ctl00_ContentPlaceHolder1_RadAjaxManager1"));
});
//]]>
</script>

I was hoping to get a solution to this from the Telerik  team. Has anyone encountered a similar occurrence?

Hello Felix,

Please review the attached project it shows how this could be implemented. In your project you should add semicolon at the end of the function's definition.

ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text","NovaCopyStlViewer('" + testFile + "');", true);
