I have encountered an interesting situation with the directive below. In order for my expressnum function to work in the template, I had to include the line
scope.expressnum = scope.expressnum();scope.expressnum = scope.expressnum();app.directive('simplyIsolated', function () {
return{
restrict: 'EA',
replace: true,
scope:{
attnum: '@numone'
,bindnum: '=numtwo'
,expressnum: '&sq'
}
,link: function (scope, elem, attr){
scope.expressnum = scope.expressnum();
}
,template:'<div><p> using "@" = {{attnum+attnum}}</p>'+
'<p>using "=" {{bindnum+bindnum}}</p>'+
'<p>using "&" {{expressnum(bindnum)}}</p><br/><p>{{y}}</p>'+
'</div>'
};
});
