Ionic send local notifications while app close

My app is content on flight schedule and every thing working fine . i have put button , that button when user click on he will receive local notifications about flight status he want . l used to cordova plugin local notifications and Background mode . l use Background mode plugin to keep my app perform infinite background execution to check flight status then send local notification to user . l used if expression to check flight status if arrived push notification if not keep looping . Even l used set Interval to keep data reloading to check flight status . All those steps i did i didn’t get any notification even though if status of flight is arrived
