title: AngularJS - reset of $scope.value doesn't change value in template (random behavior)
body: <p>Take a look at example on <a href="http://jsfiddle.net/2NJ7y/3/" rel="noreferrer">http://jsfiddle.net/2NJ7y/3/</a> (version of AngularJS 1.0.1). There is simple app, which is waiting for entering of lucky number. If the number is equal to 7, I reset lucky number to null. If I enter number 7 several times, sometime/randomly the lucky number stay in input field. Why? How this behavior solve? Thanks.</p>
