I generally do it when rendering the HTML for the control and depending on whether it's a library injection or an instance injection I use the Items collection to specify whether or not I have already produced the code for a control of this type during the current request using a unique identifier.

Something to the effect of:

    protected override void Render(HtmlTextWriter writer)
    {
        base.Render(writer);

        //Check if the Object Script has already been rendered during this request.
        if (!Context.Items.Contains("xxx"))
        {
            //Specify that the Object Script has been rendered during this request.
            Context.Items.Add("xxx", string.Empty);
            //Write the script to the page via the control
            writer.Write([libraryinjection]);
        }
        //Write the script that instantiates a new instance for this control
        writer.Write([instanceinjection]);
    }
