Title: Event bubble up to click row but e.target has already gone

Don't know if this situation is specific to me or not. My case:

1) Opened a jquery-ui dialog, with grid inside
2) grid initialized and loaded with data, with one of the cell format as a hyperlink
3) the link has a delegation, which will clear grid data

```javascript
$("#list").delegate("a", "click", function(){
$("#target").val($(this).data('xxx'));
$("list").clearGridData();
$("dialog").dialog("close");
});
```

4) When `a` is clicked, the event bubble up to `grid.hdiv`, which has a click event to handle selection. In that event, it try to locate `table.ui-jqgrid-btable`:

```javascript
$(td,ts).closest("table.ui-jqgrid-btable")[0].id.replace("_frozen","")
```
but `table.ui-jqgrid-btable` would not be found as `clearGridData` already "detached" the rows from the table, and thus exception occur.

Normally by `return false` in `delegate` should solve the problem but I think the grid itself should also avoid this.
