Doucment.location.reload not working in Chrome (but works on firefox &explorer)

When im calling facebook login and pressing login the callback function is called
i can see the alert box with the text “here”
but the window is reloaded to blank page in Chrome
but works good on firefox/explorer
why is that happening?

login.facebook_login({
				callback:function() { login.join_community(network_id,false, function() { alert("here"); document.location.reload(true); }); },
				network_url : this.network_url
			});	

location is a property of the window object and not the document object.

even when im using window.location its reloading a blank page in the canvas :S
