If you want to use parameters, try this example:

var x = "OK";
setTimeout(alertOK.bind(null,x), 3000);
x = "Would be WRONG";
console.log("before timeout:", x);

function alertOK(x){
	console.log("after timeout:",x);
}

It also works when in loop (where creating functions is not advisable).

The best way to do this would be to pass an anonymous function to setTimeout. This anonymous function will be able to access id

setTimeout(function() { showGrid(id); }, 5000);

Passing a string to setTimeout (instead of a function) is usually considered evil, since the string will be eval'd, and should be avoided.

Also note that you had a slight typo in your code: the function is setTimeout, not setTimeOut (note the lowercase o)

EDIT

Based on your comment, the code would look like this:

setTimeout(function() { document.getElementById().inerHTML = data; }, 500);

except of course you need to pass some sort of id to document.getElementById
