Set 2 headers not working

I followed the examples to show 2 headers, 1 row is going to be a text box, that when they enter something and hit enter, it should search that column for matching values, if it does, to scroll to that area.

Here is what i have.

obj.setId("myGrid");
obj.setHeaderCount(2);
obj.setHeaderTemplate(input1, 0,1);

The problem is i dont see the 2nd row should up wth the text box.
if i make it just

obj.setId("myGrid");
obj.setHeaderCount(2);
obj.setHeaderTemplate(input1, 0);

it shows up in header, but i dont want it there.

also in my function,
input1.onControlValidated = function(text){
alert(text);
}
how do i make it search all values of that column, and if it matches a value to scroll to that spot?
