I've resolved the issueI've resolved the issue be the following way:

static navigationOptions = ({ navigation }) => {
    return {
        headerRight: () => (

            
                Sync
            
        ),
    };
};

componentDidMount() {
    this.props.navigation.setParams({ onPressSyncButton: this._onPressSyncButton });
}

_onPressSyncButton = () => {
     console.log("function called");
}
