WebBrowser DocumentCompleted is useless in my case

First of all I've repaired WebBrowser and now I see the page correctly in my Windows Form. I folowed this link and referenced it to IE 11.0 so the WebBrowser control in my windows form is a IE11.0 browser instance.

I have this in the constructor of the form:

webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(WebBrowser_DocumentCompleted);

then the event handler

public void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    { 
        txtLoad.Text = (Convert.ToInt32((txtLoad.Text)) + 1).ToString();
        var webBrowser = sender as WebBrowser;
        webBrowser.Document.GetElementById("gwt-uid-126").InvokeMember("click");
    }

It all starts with a click of a button :

void BtnTestClick(object sender, EventArgs e)
    {
        webBrowser1.Navigate(@"https://play.google.com/apps/publish/?dev_acc=06010154238306490792#AppListPlace");
    }

The click invoke does nothing . I tried all methods listed here and nothing. Why can I see the button on my screen but cannot reference it in code? Why is documentCompleted firing if the button didn't load already? How can I get the button? and click it?

Fix:

webBrowser1.Navigate(@"https://play.google.com/apps/publish/?dev_acc=06010154238306490792#AppListPlace");
while (WebBrowser1.ReadyState != WebBrowserReadyState.Complete) {
         txtLoad.Text = WebBrowser1.ReadyState.ToString();
        Application.DoEvents();
        System.Threading.Thread.Sleep(1);
    }
webBrowser1.Document.GetElementById("gwt-uid-126").InvokeMember("click");


there i a call to the WebBrowserDocumentCompleted event even if the document is not fully loaded.
example:
lets say that there are 2 script elements inside the page source code:

<script src="1.js"></script>
//Here There Is A Call To WebBrowserDocumentCompleted 
<script src="2.js"></script>
//Here There Is A Call To WebBrowserDocumentCompleted
............
body
.............
</html>
//Here There Is A Call To WebBrowserDocumentCompleted

the webbrowser is calling this event even after he done loading script/stylesheet - the page is not really fully loaded yet.
