Title: buttonClickSelector must have data-url attribute

If no data url button which is like a form child button, it'll failure to fire correct handler.

So, I fixed the behavior.

Following example is not "buttonClickSelector".
```

```

Following example is "buttonClickSelector".
```
// this button is not form child

```
