how to modify 2d array in function c++

void Insert_into_2D_Array(int** foo, int x_pos, int y_pos, int x_size, int y_size)
{
    int insert_value = 10;

    if (x_pos < x_size && y_pos < y_size) {
        foo[x_pos][y_pos] = insert_value;    // insert_value lost post func exit
    }
}

int** Init_2D_Array(int x_size, int y_size)
{

    int** foo = new int*[x_size];    // new alloc mem lost post func exit  
    for (int i = 0; i<x_size; i++)
    {
        foo[i] = new int[y_size];     // new alloc mem lost post func exit
    }

    return foo;
}

int main()
{

    int** foo;
    int x_size = 10, y_size = 10;
    foo = Init_2D_Array(x_size, y_size);
    Insert_into_2D_Array(foo, 3, 3, x_size, y_size);

    return 0;
}
