Question

i am using scroll view in react-native to move the view, i wrote like this scrollView.scrollTo({ y: newY, animated: true });

scrolldown(){

<ScrollView ref='ScrollView'>
                 <View style={styles.inputContainer}>
             <Image style={styles.inputPassword} source={require('image!locker')}/>
             <TextInput
               ref='SecondInput'
               password={true}
               style={styles.email}
               value={this.state.password} 
               placeholder="Password"
               onFocus={this.scrolldown.bind(this)}
               returnKeyType='next'
