Number of numbers in a character array

I am trying to count the number of ones in a character array that represent a binary number with a recursive type program. However, it seems that my program is just counting the number of characters in the array. I don't know if I am just comparing wrong or not, but I cannot find the problem

#include <stdio.h>
# include <stdlib.h>
#include <string.h>
#define SIZE 20

int determine (char array[SIZE], int count, int track );

int main()
{ 
int answer = 0; 
char input[SIZE]={"1001001"};
int count = 0;
int track = 0;

answer = determine(input, count, track);

 printf("The number of 1 is %d ", answer);

system("PAUSE");
return 0;
 }

 int determine(char array[], int count, int track)
{   

 if (array[track] != '\0')
 {
    if ( array[track] == '1');
    {
         count++;
    }
    return determine(array, count, track = track+1);    
 }
 else 
 {
      return count;
 }
}
