How to set the caret position, there is only
this.caretIndex (READ)

The first expected parameter is the ID of the element you wish to insert the keyboard caret on. If the element is unable to be found, nothing will happen (obviously). The second parameter is the caret positon index. Zero will put the keyboard caret at the beginning.
If you ever had a specific case where you had to retrieve the position of a caret (your cursor's position) inside an HTML input field, you can do so using the selectionStart property of an input's value.
To move the cursor to the end of an input field: Use the setSelectionRange() method to set the current text selection position to the end of the input field. Call the focus() method on the input element. The focus method will move the cursor to the end of the input element's value.
use setSelection(beginIndex:int, endIndex:int):void
eg
this.textField.setSelection(20, 20)
