How to send a multi-column harness on a single button with ng-repeat and angular

I have a form in grid format, in it I present information from the table Itens of my bank (74 total). The intent of this grid form is to add two fields: price and bdi price in all these items.

My problem is that I can not send the information of the 74 records in a single button.

I'm using ng-repeat in the table to show the 74 items in my grid form, and even in this ng-repeat I have the inputs.

HTML:

<div class="table-responsive">
<table class="table table-bordered table-hover table-condensed">
    <thead>
        <tr id="fundocoreditarcd">
            <th>Código Tipo Item</th>
            <th>Código Item</th>
            <th>Descrição</th>
            <th>Preço</th>
            <th>Preço BDI</th>
            <th>Ações</th>
        </tr>
    </thead>
    <tbody>
        <tr ng-repeat="item in itens">
            <td>{{item.tipo_item_cod_tipo_item}}</td>
            <td>{{item.cod_item}}</td>
            <td>{{item.descricao}}</td>
            <td><input type="text" ng-model="item.preco" class="money" id="preco" /></td>
            <td><input type="text" ng-model="item.precoBdi" class="money" id="bdi" /></td>
            <td><a href="/cid/editarLote"><span class="glyphicon glyphicon-pencil"></span></a> <a href="http://geradormemes.com/media/created/8kbx7r.jpg" class=""><span class="glyphicon glyphicon-trash"></span></a> </td>

        </tr>
    </tbody>

    <button ng-click="addPrecoItens(item)" class="btn btn-primary">Enviar</button>
</table>

Part of the JS controller:

$http.get("read/itens")
.success(function (item) {
    $scope.itens = item;
    console.log($scope.itens);
})
.error(function (erro) {
    console.log(erro);
});

$scope.addPrecoItens = function (item) {
$scope.itensLote = item;
console.log($scope.itensLote);
/*$http.put('read/itens/', $scope.itensLote)
    .success(function () {
        console.log($scope.itensLote);
        $scope.mensagem = 'itens editados!';
    })
    .error(function (erro) {
        $scope.mensagem = 'Erro ao editar itens!';
        console.log(erro)
    });*/
};
