React-native: Load Images dynamically from state

Hi everybody,

I have an issue where I try to change the image source from a change in the state object but it's not changing.
I have logged the value and it's changing but the image does not.

Here it's the code im using:

render() {
        var images = {
            playcircle: require('image!playcircle'),
            pausecircle: require('image!pausecircle')
        }
        return (
            <View style={[styles.container, {width: this.props.width - 10}]}>
                <TouchableOpacity onPress={this._playAudio.bind(this)}>
                    <Image source={images[this.state.playImage]} style={styles.img} />
                </TouchableOpacity>
                <View style={styles.textWrapper}>
                    <Text style={styles.txt}>{this.props.podTitle}</Text>
                </View>
            </View>
        );
    }

_playAudio() {
        var blockThis = this;
        debugger;
        if (!this.state.isPlaying) {
            JSAudioPlayer.play(this.props.url, true, function(error){
                if (error) {
                    alert(error);
                } else {
                    blockThis.setState({
                        isPlaying: true,
                        playImage: 'pausecircle'
                    })
                }
            });
        } else {
            JSAudioPlayer.pauseCurrent();
            blockThis.setState({
                isPlaying: false,
                playImage: 'playcircle'
            });
        }       
    }

Any help will be appreciated.
Thanks in advance
