How to change the default text created using drawText

[mfarook]

I am using drawfeature directive to draw point, line, polygon and text in map. Everything works fine except, when using drawText the default text gets created based on the number of features created using point,polygon and line. For ex: If there are 10 features created already, then the text created using drawText is text11. How can i change this behaviour to add my own text from keyboard?
