wrong output with linked list program

I have written below program which creates a new linked list and prints its elements. The problem I face here is that when i print the values, only the value of last node gets printed and that too several times. Please have a look and tell me what am i doing wrong in this program.

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>

struct node
{
       int data;
       struct node *link;
}*head=NULL;

void print()
{
     struct node *temp=NULL;
     temp=head;
     while(temp!=NULL)
     {
                    printf("%d", temp->data);
                      temp=temp->link;
     }
     printf("NULL");
}
void create_list()
{
     int value;char ch;
     struct node *new_node=(struct node*)malloc(sizeof(struct node*));
      struct node *current=NULL;
    printf("before do\n");
     do{


    printf("enter the data \n");
    scanf("%d", &value);
    new_node->data=value;
    new_node->link=NULL;
     if(head==NULL)
     {
                   head=new_node;
                   current=new_node;
     }
     else
     {

      current->link=new_node;
      current=new_node;
      }                
     printf("do you want to create another  node \n");
     ch=getche();
     }while(ch=='Y');

}





int main()
{
    create_list();
    print();
   getchar();
     return 0;
}

Input and output:

enter the data
2
do you want to create another  node 
Y
enter the data
3
do you want to create another  node 
Y
enter the data
4
do you want to create another  node 
Y
enter the data
5
do you want to create another  node 
N
