Back button event is not being fired in Enterprise browser in Windows Mobile using Webkit engine.
 
To test this bug, I have created a test page with following code. It worked for other keys except for "bksp".
When I use backspace key while focus is on a text field, then it seems to work. Following is my code which is pretty straight forward
 

   
   
      
   
 
        function CallB(event) {          
            alert(event.keyCode); 
        }
        $(window).on("keydown keypress keyup", CallB); //I also tried $(document)
