reloadGrid fails because of p not initialized.

Property p is not correctly initialized.

Thanks for pointing of that! Currently reloadGrid works correctly, but p will be used from the outer scope, which has some minor disadvantages. I agree, that it would be better to define local variable via p = self.p. On the other side, your last changes (see here) don't declare local variable p and just overwrite p defined in the outer scope. Such code have no advantage comparing with the current code of free jqGrid. Thus I'm closing your pull request and declare p = self.p (like here) in the separate commit.
