How to display contents in the drop-down successfully

Im using ionic to develop an app.Here Im trying to cascade drop-down box and list, so that when an option is selected from drop-down the list will display options related to the selection made in the drop-down. Here Im not getting the options in the drop-down as well as in list so can anyone explain what has to be done and what is the mistake?

//$scope.sample=“Inside the cartype ctrl”;

{‘name’:‘Benz’, ‘types’:[‘SUV’, ‘Sedan’]},
{‘name’:‘BMW’, ‘types’:[‘SUV’, ‘Sedan’, ‘Van’]}

$scope.home = function () {


I have tried many methods to achieve it but couldn’t get success please do help me to find the correct answer.
