[webkit-gtk] Access web view in g_signal_callback

I am using GTK 3.12 and GTK WebKit 2 and I have a g_signal_callback that I
want to change the HTML content of the web view on click basically.

So I have a

struct data {
    WebKitWebView *web_view;

And I start the webview and add it too my window

data.web_view = (WebKitWebView *) webkit_web_view_new();
GtkWidget *web_window = gtk_scrolled_window_new(NULL, NULL);
gtk_container_add(GTK_CONTAINER(web_window), GTK_WIDGET(notes.web_view));

And then I have a signal

g_signal_connect(blah, "blah", G_CALLBACK(function), &data);

And a function

void function(struct data *blah) {
    webkit_web_view_load_html(blah->web_view, html, NULL);

And everything but the callback works, when I press the button I get

** CRITICAL **: void webkit_web_view_load_html(WebKitWebView*, const
gchar*, const gchar*): assertion 'WEBKIT_IS_WEB_VIEW(webView)' failed

But the passed in value is the webview, I've also tried not using a struct
and it still isn't working.

Any ideas on what could be wrong? Do I need to wait for it too load or do
something else? I see the HTML (it's only <h1>Hello</h1> so it shouldn't
take long) before I press the button.
