ASP.NET failing to execute Javascript

Can you take a look at this code and help me figure out why the alert is not working on the webpage? The console.WriteLine statement below it is running fine, but the alert isn't appearing.


    private void PublishLoop()
    {
        while (Running)
        {          
            Thread.Sleep(5000);
            dtMessages = (String)(Cache.Get(key));
            if (dtMessages == null)
            {
                //publish here
                dtMessages = LoadMessages();
                System.Diagnostics.Debugger.Log(0,null,dtMessages);
                Page.ClientScript.RegisterStartupScript(this.GetType(),"ClientScript", "alert('hi');",true);
                Console.WriteLine(dtMessages);
            }
        }
     }

Update: Make sure to note that only one unique key can be registered per response. The issue arises from executing this line of code within a while loop, causing the same key to be registered repeatedly. To circumvent this problem, provide a distinct key parameter each time the function is invoked. For example, consider incorporating a counter in your loop and appending it to the key string.

int i = 0;
while (Running)
        {          
            Thread.Sleep(5000);
            dtMessages = (String)(Cache.Get(key));
            if (dtMessages == null)
            {
                //execute publishing logic here
                dtMessages = LoadMessages();
                System.Diagnostics.Debugger.Log(0,null,dtMessages);
                Page.ClientScript.RegisterStartupScript(this.GetType(),"ClientScript" + i.ToString(), "alert('hi');",true);
                Console.WriteLine(dtMessages);
                i++;
            }
        }
