When I use angular 1.3, I am used this (Detect Unsaved changes and alert user using angularjs) to detect unsaved change and alert to user, everything work fine. But when use angular 1.5 (component router) the value of $ctrl.form.$dirty was destroyed after $locationChangeStart so I can't get this value( before $locationChangeStart, this value show correctly when I debug by show it on the html code)
Anyone have suggestion Thank so much!
