I think you should provide the ids)property) to the textboxes and that's too in pattern.

Like if you have three textboxes initialy with ids tb1 , tb2,tb3 respectively.

Then fill the id attribute of dynamicaly created textbox with tb4(where 4 is from some counter

value or you may get it from getElementsByTagName("input").length).

Finaly,

through getElementById("tb"+counter).value=someValue you can insert value to the dynamicaly created textbox.

Best Of Luck..
