Cannot read property 'navigation' of undefined - react native

I am developing a react native app. In that app When I am calling the following function I am getting an error

Cannot read property 'navigation' of undefined

      handleForgotPassword = (email) => {
        firebase.auth().sendPasswordResetEmail(email)
        .then(function (user) {
          console.log("Inner");
          this.props.navigation.navigate("Login") //not working
        }).catch(function (e) {
          console.log(e)
        })

      }

But on the same page, I am using this following code and it is working fine.

<TouchableOpacity onPress={() => this.props.navigation.navigate("Login")}> //but this is working
      <Image  source={require('../src/Assets/close.png')} />
      </TouchableOpacity>

Can anyone please tell me what is the problem

Anonymous function has it's own context (that's why navigation is undefined) ... but arrow function is automatically bound to it's parent

       firebase.auth().sendPasswordResetEmail(email)
        .then((user) =>  {
          console.log("Inner");
          this.props.navigation.navigate("Login") // Will work
        })
