$uibModal tries force execute submit in my form - angularjs

Question

I have a modal dialog, created with ui.bootstrap. When I'm performing some code with $uibModal or $uibModalInstance, inside of controller of this modal, AngularJS try to call submit method of my <form> from dialog. Also, my <form> hasn't a submit attribute, but it has a ng-submit attribute.
Here is a part of my modal dialog:
<div class="modal-content">
<form name="newActionForm" class="form-horizontal" role="form" ng-submit="">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title">{{ 'action.labelNewAction' | translate }}</h4>
</div>
<div class="modal-body">
<div class="form-group">
<label class="col-sm-3 control-label site-form-label">{{ 'common.labelName' | translate }}:</label>
<div class="col-sm-9 input-group padding_right_left_15" ng-class=" newActionForm.name.$valid ? 'has-success' : 'has-error' ">
<input required ng-maxlength="160" ng-change="vm.test()" name="name" class="form-control" ng-model="vm.newAction.name"/>
<span class="input-group-addon">
<i class="glyphicon glyphicon-remove" ng-show="newActionForm.name.$error.required" tooltip="{{'formValidationRequired' | translate}}"></i>
<i class="glyphicon glyphicon-remove" ng-show="newActionForm.name.$error.maxlength" tooltip="{{'formValidationNameTooLong' | translate}}"></i>
<i class="glyphicon glyphicon-ok" ng-show="newActionForm.name.$valid"></i>
</span>
</div>
</div>
</div>
<div class="modal-footer">
<button ng-disabled="newActionForm.$invalid" class="btn btn_kassir" ng-click="vm.addAction()">{{ 'common.labelButtonAdd' | translate }}</button>
<button class="btn btn-default" ng-click="close()">{{ 'common.labelButtonClose' | translate }}</button>
</div>
</form>
</div>
and modal contoller with two functions, that tries to perform sumbit on my form:
angular
.module('newActionDialog')
.controller('NewActionDialogController',
[ '$scope', '$stateParams', '$uibModalInstance', 'Requester', '$uibModal', '$filter', '$translate', 'alertService', NewActionDialogController]);
function NewActionDialogController($scope, $stateParams, $uibModalInstance, Requester, $uibModal, $filter, $translate, alertService) {
var vm = this;
vm.showSelectHall=function(){
$uibModal.open({
templateUrl: 'app/repertoire/listHalls.html',
controller: function ($scope, $uibModalInstance) {
this.select = function (hallConfig) {
$uibModalInstance.close(hallConfig);
};
},
controllerAs: 'ctrl',
}).result.then(function (hallConfig) {
vm.newAction.defaultHallConfiguration=hallConfig;
});
};
......
vm.close=function(){
$uibModalInstance.close();
}
}

The issue has been solved and it was occuring because of the $uibModal.open() method creates a modal with a <buttons type="submit"> by default. So, after $uibModal.open() <button> transformed to <button type="submit>. Solution is add to all buttons type="button", except real submit button, of course.
