Changing Text component value in runtime

I'm trying to get a <Text> component in the view and edit its value in runtime.

What I tried:

<Text ref="SignInMessage">qqq</Text>

Then to get and change the text I do this.refs.SignInMessage.props.children = err.message but it doesn't change.

I also tried:

<Text>{this.SignInMessage}</Text>

And then this.SignInMessage = err.message; but it also doesn't change.

You can use state to update the value 

this.state({ SignInMessage: '' }); // initialize

this.setState({ SignInMessage: 'bl bla'}); // update

<Text>{this.state.SignInMessage}</Text>
