Possible Unhandled Promise Rejection

[hophoppoppop]

So i have this code:

`constructor(props){
super(props);
this._fbAuth = this._fbAuth.bind(this);
this.login = this.login.bind(this);
}

login(){
this.props.navigator.push({
id: "Home",
});
}

_fbAuth(){
LoginManager.logInWithReadPermissions(['public_profile']).then(
function(result) {
if (result.isCancelled) {
alert('Login cancelled');
} else {
alert('Login success with permissions: '+result.grantedPermissions.toString());
this.login();
}
},
function(error) {
alert('Login fail with error: ' + error);
}
);
}`

Everytime after i try login with facebook. It's success but always give warning
"Possible: Unhandled Promise Rejection (id: 0): Type Error: Undefined is not a function (Evaluating 'this.login()')".

i try bind the auth function and login function in constructor but the warning still pop up.
