Create angular variable in html

Hello

I have a loop (ng-repeat) in my html file and would like to save the index of it in a variable to be able to pass parameter to a function.

Does anyone have an idea how I can do this?

Follow the code in View:

<div class="lista_cores">
    <div class="opcao_tamanho col-xs-12" ng-repeat="tamanho in vm.tamanho">
    {{vm.index = $index}}
        <div class="lista_cores" ng-repeat="cor in tamanho.cor track by $index">
            <button type="button" class="btn_remove" ng-click="vm.removeCor(vm.index, $index)"><span class="glyphicon glyphicon-remove"></span></button>
        </div>
        <button type="button" class="btn_adiciona" ng-click="vm.addCor($index)">Adicionar cor</button>
    </div>
    <button type="button" class="btn_remove" ng-click="vm.removeTamanho($index)"><span class="glyphicon glyphicon-remove"></span></button>
</div>
<button type="button" class="btn_adiciona" ng-click="vm.addTamanho($index)">Adicionar tamanho</button>

Function on Controller:

vm.tamanho = [{
        "nome_produto_tamanho": "",
        "cor": [{
            "nome_produto_cor": ""
        }]
    }];
    vm.addTamanho = function(index){
        vm.tamanho.push({
            "nome_produto_tamanho": "",
            "cor": [{
                "nome_produto_cor": ""
            }]
        });
    }
    vm.removeTamanho = function(index) {
        vm.tamanho.splice(index, 1);
    };

    vm.cores = {
        "nome_produto_cor": ""
    };
    vm.addCor = function(id_tamanho){
        vm.tamanho[id_tamanho].cor.push(vm.cores);
    }
    vm.removeCor = function(id_tamanho, index) {
        console.log(index);
        console.log(id_tamanho);
        vm.tamanho[id_tamanho].cor.splice(index, 1);
    };

The code has been greatly simplified, but it's basically the part that matters.

The user can add color and size by clicking a button and remove also, my problem is when removing an added color, since I need the size id to be able to delete the color.
