javascript - Getting an input's current value in a keypress event in angularjs -

-

i'm trying add dirty class input while user typing. i'v created directive binds keydown event , checks value against last saved one. 

elm.bind('keydown', function(event) {     if (event.which === 13)        scope.update();      else if ( scope.last_saved_value !== elm.val() )         elm.addclass('dirty-input'); });

jsbin full example

to see problem, change value in input , press enter. works fine. now, add number , you'll see field not become dirty , event capturing previous value , not current. guess elm.val() \ model.$viewvalue being updated after event taken care of (to allow manipulation on value).

so how can capture current value on keydown ?
