Clickable Link Not appearing on page from generate

Question

I have some .js code that generates the following anchor tag:

<a name="link_274_4" id="link_274" onserverclick="DownloadInspection_Click" runat="server">2017-09-10</a>

I cut and paste that out of the DOM Explorer of IE.

That link is not clickable on the page that I am displaying.

Here is the vb.net that I want it to run:

Sub DownloadInspection_Click(ByVal sender As Object, ByVal e As EventArgs)
    Dim button As Button = DirectCast(sender, Button)
    Dim pk As Integer = CInt(button.ID.Replace("link_", ""))

    Dim FileNamePrefix As String = CStr(pk)

    Dim PreApprovalDir = "C:\\Data"

    Dim di As New DirectoryInfo(PreApprovalDir)
    Dim fiArr As FileInfo() = di.GetFiles()
    Dim fri As FileInfo
    For Each fri In fiArr
        If fri.Name.StartsWith(FileNamePrefix) Then
            Exit For
        End If
    Next fri


    Response.Clear()
    Response.AddHeader("Content-Disposition", "attachment; filename=" + fri.Name)
    Response.ContentType = "application/octet-stream"

    Response.AddHeader("Content-Length", fri.Length)
    Response.WriteFile(fri.FullName)
    Response.End()

End Sub

I would have expected the VB to need a Handles Clause, but this SO post does not have it: Running a code behind routine from an <a href

The anchor tags are generated in a table so I would not know what the code as the Handles clause.
