Atalasoft Wingscan ImportDocument Not Being Called When Importing

Question

I am trying to scan through a browser using Atalasoft's Wingscan product. I have the scan working correctly, however the upload to the appropriate server directory is not working. I am using the
button as described in the Wingscan sample documentation. The expected behavior would be to access the overriden ImportDocument function and perform the required business logic.

Protected Overrides Function ImportDocument(context As HttpContext, filename As String, contentType As String, contentTypeDocumentClass As String, contentTypeDescription As String) As Dictionary(Of String, String)

When debugging the function is never accessed. Any ideas or suggestion would be greatly appreciated.

Thanks for any and all assistance!!!

Was missing the following code

 Atalasoft.Controls.Capture.CaptureService.initialize({
                handlerUrl: 'ScanningHandler.ashx'
            });
