how to re write this program, if i am click the button then image should blink.

if I use this code, automatically blinking started without button click, I have to control the blink using button.

Now My Question is:

How to control the blink using button, how should I write the JS.

$scope.blinkInterval = 0;

$scope.blinkImage = function(id) {
 var current = $scope.view.wdg[id].visible;
 if (current == undefined) { current = true;}
 $scope.setWidgetProp(id, "visible", !current);
}

$scope.startBlink = function() {
 $scope.blinkInterval = $interval($scope.blinkImage, 1000, 0, true, "3DImage-1");
}

$scope.stopBlink = function(id) {
 $interval.cancel($scope.blinkInterval);
}

angular.element(document).ready($scope.startBlink);
