angularjs correct row is not being deleted from table - angularjs

Question

I have been struggling with a couple of issue so I thought I would reach out for help after doing much searching. I'm using AngularJS.
My first problem is that checkbox is not working properly when I use ng-repeat, it will only check the first box in the table code snippet below. I'm using a custom checkbox which I coded with css is the reason for the label.
My second issue is when I click on the check box it should delete any row I want but it deletes the row before it if I start from the bottom of the table up, but if I start from the top of the table down it works as expected except for the box being checked code snippet. I tried many ways to set the index but it still does not work.
$scope.removeRow = function(type) {
var index = -1;
var myArr = eval( $scope.contacts );
for( var i = 0; i < myArr.length; i++ ) {
if( myArr[i].type === type ) {
index = i;
break;
}
{
if( index === -1 ) {
alert( "Something gone wrong" );
}
$scope.contacts.splice(index, 1);
};

First off, don't use eval($scope.contacts). If that variable is a string and contains javascript it will run that javascript. if myArr isn't defined using myArr = $scope.contacts you can use myArr = JSON.parse(JSON.stringify($scope.contacts) or use angular.copy method.
I don't see your html, so I can't tell you why your checkbox doesn't work. But regarding your second problem, if it's deleting a row above when you hit splice, why not change that code to :
$scope.contacts.splice(index + 1, 1)
