Angular UI Grid not updating directives in cells - angular-ui-grid

Question

I have a ui grid that contains a directive, this directive has an isolated scope and changes it's template basing on some logic.
The problem is that, when sorting (and also when PAGING), the 'logic' of the directive seems to not be correctly "re-evaluated".
In the specific example, the rightmost column should only see some "11" while if you try to sort by id (or the other fields) you'll see some spurios '0' appearing.
this is the ui:
<div ng-app="myapp">
<div ng-controller="myctrl">
<div ui-grid="gridOptions" ng-style="gridStyle"></div>
</div>
</div>
this is the js:
var myapp = angular.module('myapp', ["ngRoute", "ui.grid"])
.controller('myctrl', function($scope) {
$scope.gridOptions = {
data: [{
id: 1,
name: "Max",
other: "pippo",
number: 1
}, {
id: 2,
name: "Adam",
other: "pluto",
number: 0
}, {
id: 3,
name: "Betty",
other: "paperino",
number: 0
}, {
id: 4,
name: "Sara",
other: "fava",
number: 1
}, {
id: 5,
name: "Favonio",
other: "favona",
number: 1
}],
columnDefs: [{
field: "id",
displayName: "ID"
}, {
field: "name",
displayName: "Name"
}, {
field: "other",
displayName: "Other"
}, {
field: "number",
cellTemplate: '<div class="ui-grid-cell-contents"><mydir data="row.entity"></mydir></div>'
}]
};
}).directive("mydir", function() {
return {
restrict: 'E',
scope: {
data: "=",
},
template: '<div><label ng-if="data.number==1">{{set}}</label></div>',
link: function(scope, iElement, iAttrs) {
scope.set = -1;
if (scope.data.number == 0) {
scope.set = 00;
} else {
scope.set = 11;
}
}
}
});

Any hint?

In the end it's a known bug:

And I solved using watch like it's said here:
