C: Creating new struct object with char* in loop but char* reammins same for all the objects after loop

Question

What i am trying to do is reading information from text file and store it in struct person.

I tried to store multiple persons information in array of struct. My code works for integer values but every persons name is the same, somehow all the persons name is the last persons name. I am new on c so dont know exactly how this memory works but if i print my array in while loop everything seems fine but if i try to print array outside of assignment loop names reamins same.

This is my Person struct:

typedef enum Bool{false, true}boolean;

struct PERSON{
    char *name;
    float money;
    float betAmount;
    int betNumber;

boolean (*isWin)(struct KISI*,int);
void (*delete)(struct KISI*);
};
typedef struct PERSON* Person;
Person new_Kisi(char*,float,float,int);
void delete_Kisi(const Person);

This is the Person.c:

Person new_Kisi(char* name,float money,float betAmount, int betNumber)
{
    Person this;
    this = (Person)malloc(sizeof(struct PERSON));
    this->name=name;
    this->money = money;
    this->betAmount = betAmount;
    this-> betNumber = betNumber;
    this->delete = &delete_Kisi;
    return this;

}

void delete_Kisi(const Person this){
    if(this==NULL) return;
    free(this);
}

This is my code so far:

FILE* fp;
    char buffer_in[256];
    fp=fopen("Kisiler.txt", "r");
    if (fp==NULL)
    {
        return 1;
    }
    
    int count_lines = 0;
    char chr;
    
    chr = getc(fp);
    while (chr != EOF)
    {
        //Count whenever new line is encountered
        if (chr == 'n')
        {
            count_lines = count_lines + 1;
        }
        //take next character from file.
        chr = getc(fp);
    }
    fclose(fp);
    fp=fopen("Kisiler.txt", "r");
    int personNum=0;
        Person persons[count_lines];
        memset(persons,0,sizeof(struct KISI)*count_lines);
        char *namePerson;
        char temp[64]={0};
        float money;
        float betAmount;
        int betNumber;

while (!feof(fp))
{
    fgets(buffer_in, 256 , fp);
    sscanf(buffer_in, "%[a-zA-Z ]#%f#%f#%d",temp,&money,&betAmount,&betNumber);
    namePerson=&temp[0];
    persons[personNum]=new_Kisi(namePerson,money,betAmount,betNumber);
    
    printf("%s %f %.2f %d \n", 
        persons[personNum]->name, persons[personNum]->money, persons[personNum]->betAmount, persons[personNum]->betNumber);

    personNum++;
}
printf("\n<<<<<<<<<<<<<<<<<<<< after while loop >>>>>>>>>>> \n");

fclose(fp);
int n=personNum;
for (int i = 0; i <n; i++)
{  
    printf("%s \n", 
        persons[i]->name);
    
}

This is the output:
