You must change the event name from  change  to  onchange      document  ready function               input tags   bind  onchange   autoFill                   or use the shortcut binder method change     document  ready function               input tags   change autoFill                   Note that the onchange event usually fires when the user leave the input  so for auto-complete you better use the keydown event

What Chad says  except its better to use  keyup in this case because with  keydown and  keypress the value of the input is still the older value i e  the newest key pressed would not be reflected if  val   is called    This should probably be a comment on Chad s answer but I dont have privileges to comment yet

Combination of keyup and change is not necessarily enough  browser s autocomplete and paste using mouse also changes the contents of a text box  but doesn t fire either of these events    jquery change not working incase of dynamic value change
