We used it before, to detect the change of text and do function:

```auto
<TextInput Value="{titleInput}" TextChanged="function"/>

```

For the updated version, error occurs:

```auto
'TextInput' does not have a property called 'TextChanged' - ...

```

I tried to use ValueChanged but did not work. Could you give me some hints? Thanks.

Hi,

`TextChanged` is renamed to `ValueChanged`.

Binding to `Value` on the `TextInput` is also a two-way binding now. `titleInput` will be automatically written to when the user changes the text. 🙂

Hi! Thank you for reply. And I’d like to ask more. Is ValueChanged support an observable function?

I tried something like that:

```auto
<TextInput Value="{titleInput}" ValueChanged="{ObservableFunction}"/>

```

js:

```auto
function ObservableFunction()
{
    debug_log ("HI");
}

```

but with error:

```auto
Exception: System.Exception: EventBinding: event must be a Fuse.NodeEvent

```

Hi,

Thanks for reporting this. This was an unintended restriction. I’ve pushed a fix, will roll out in next release.
