How can I remove :active from bootstrap button - angularjs

Question

I have a website, where I have multiple buttons. Once a button is pressed I populate a list, though my problem is that the last pressed button keeps to be looking pressed (has the :active class). I thought about using angular's $timeout to reset the button, though the removeClass function doesn't do the trick.
My view looks like this:
div(ng-controller='productButtonController')
div(ng-repeat='product in products')
div.col-md-4
button.btn.btn-block.sell-button(id='{{product._id}}' ng-click='sell()'){{product.name}}
and my controller:
app.controller('productButtonController', ['$scope', '$timeout', 'productServices', 'flash',
function($scope, $timeout, productServices, flash) {
productServices.getProducts()
.success(function(result) {
$scope.products = result.data
})
.error(showErrorMessage(flash))
$scope.sell = function() {
console.log(this.product)
that = this
$('#' + that.product._id).removeClass('active')
}
}
])

Answer 1

Add the angular $window service to your dependencies for the
controller
Call the blur method on the document's active element, which will be
your button.
$window.document.activeElement.blur();
See How do you clear the focus in javascript?.

Answer 2

This code from Justin Poehnelt's handy GIST solves this elegantly.
app.directive('blur', [function () {
return {
restrict: 'A',
link: function (scope, element) {
element.on('click', function () {
element.blur();
});
}
};
}]);
Add the blur attribute to a button/element you need blurred after click. Eg.
<button type="button" blur>Click me</button>

If you simply want to override the focus status of the bootstrap buttons you could do it with:
.btn:focus{
outline: none;
}
Then your buttons should look like:
<button class="btn btn-default">My button 1</button>
It's also important that the stylesheet which overrides the button status is loaded after the bootstrap stylesheet.
EDIT:
Sorry, but the previous step only removes the outline. The background-color of the button still remains the same.
Since bootstrap doesn't append any active classes to the clicked element as far as i know you need to change the :focus status of the button:
$('#' + that.product._id).blur();
Let me know if this works for you.
