jQuery Grid Plugin - jqGrid

Hi there,

I'm trying to add a custom button, where when someone selects a row, clicking a custom button will bring up a dialog box for that specific row. When I set up the "onClickButton" attribute with a "function(id)" it seems to crash jQuery with an error ("value = jQuery.isFunction( value ) ? value() : value; Could not convert JavaScript argument".

Here's how I'm setting it up:

.navButtonAdd('#relationships-table-pager',{
caption:"Edit",
buttonicon:"ui-icon-pencil",
onClickButton: function(id) { self.show_company(id); },
position:"first"
});

When I set up "onClickButton" as "function() { ... }", then I can run the function fine. I thought running function(id) is how one would validly access a row's id for a function. It seems like it might be a bug, but wanted to see if others have seen this problem. Any input would also be great. Thanks!
