Problem submitting form

I’m trying to submit sign up form in my react native PROJECT. When i press the button nothing seem to happen not even logging anything to the console. Below are the codes:

import { useState } from 'react';
import { useAuthContext } from './useAuthContext';
import AsyncStorage from '@react-native-async-storage/async-storage';

export const useSignup = () => {
  const [error, setError] = useState(null);
  const [loading, setLoading] = useState(null);

  const { dispatch } = useAuthContext();

  const signup = async (name, email, password) => {
    setLoading(true);
    setError(false);

    const response = await fetch('http://localhost:8000/api/users/signup', {
      method: 'POST',
      headers: { 'content-type': 'application/json' },
      body: JSON.stringify({ name, email, password }),
    });

    const json = await response.json();

    if (!response.ok) {
      setLoading(false);
      setError(json.error);
    }

    if (response.ok) {
      try {
        await AsyncStorage.setItem('user', JSON.stringify(json));
      } catch (e) {
        console.log('Error saving data to storage', e);
      }

      dispatch({ type: 'LOGIN', payload: json });
      setLoading(false);
    }
  };

  return {
    signup,
    loading,
    error,
  };
};
import React, { useState } from 'react';
import {
  ActivityIndicator,
  Image,
  Keyboard,
  Pressable,
  StyleSheet,
  Text,
  TouchableOpacity,
  View,
} from 'react-native';
import { useSignup } from '../hooks/useSignup';
import {
  TextInput,
  TouchableWithoutFeedback,
} from 'react-native-gesture-handler';
import { useNavigation } from '@react-navigation/native';

const logo = require('frontend/assets/images/undraw_Sign_up_n6im.png');

const SignupScreen = () => {
  const [name, setName] = useState('');
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  const [isError, setIsError] = useState({});
  const { signup, loading, error } = useSignup();
  const navigation = useNavigation();

  const validationForm = () => {
    let isError = {};
    if (!name) isError.name = 'Name is required';
    if (!email) isError.email = 'Email is required';
    if (!password) isError.password = 'Password is required';

    setIsError(isError);
    return Object.keys(isError).length === 0;
  };

  const handleSubmit = async () => {
    if (validationForm()) {
      console.log('Submitted', name, email);
      await signup(name, email, password);
      console.log('Form data before signup:', name, email, password);
      setName('');
      setEmail('');
      setPassword('');
      setIsError({});
    }

    navigation.navigate('SigninScreen');
  };
