Your ng-options data is MainCategory and your ng-model is binded to it as well. This means that selecting an options turns your data to one value only - your selected option. In your case you should have a data property, lets say - categories. Like this:

ng-options="main.Name for main in categories track by main.ID"

In addition you will hold in your controller another property for the selected Category and ng-model will bind to it:
