[webkit-gtk] how to simulate mouse click event

[green]

Hi:
         I was working with WebKitGtk2 some time, and I found something 
puzzle.
         when I use mouse click some <a> label on a website, it transfer 
some verify, if it was a humankind or not, checking with AJAX behind.
         Then I use the javascript to trigging its click event, but It 
doesn't transfer any AJAX network connection. I found it with the Inspector.
         Is there any way I can simulate webkitgtk2 as a human do the click?

Best Regards
