Consider this scenario:
<input ng-model="selectedColor" type="text"></input>
This approach will not produce the desired outcome:
<p ng-click="changeColor($index)">change color</p>
Is there another way to access $index without using a loop?

Instead of keeping track of the index, you can easily remove the selectedCategory from the categories model by modifying the removeCategory function:
Check out this example controller on JSFiddle:
app.controller("myCtrl", ['$scope', function($scope){
$scope.model = {
selectedCategory: {},
categories: [
{title: "Cat1"},
{title: "Cat2"}
]
}
//init
$scope.model.selectedCategory = $scope.model.categories[0];
$scope.removeCategory = function(){
var ind = $scope.model.categories.indexOf( $scope.model.selectedCategory );
$scope.model.categories.splice( ind, 1 );
$scope.model.selectedCategory = $scope.model.categories[0];
}
}])
