angularjs - Creating button with ng-repeat that has an array with functions -

-

i have array of objects 2 keys. key label text go on button. , action, function want happen when user clicks (ng-click) button. when this, no error thrown, function not work :(

my js:

var mybtns = [{     label: 'btn1',     action: function() {         alert('hi')     } }];

my html inside directive this:

<button type="button" ng-repeat="abtninfo in mybtns" ng-click="abtninfo.action()">      abtninfo.label </button>

here simple fiddle: http://jsfiddle.net/ppe34vlj/1/

on other hand if try <button ng-click="{{abtninfo.action}}">, throws error:

> "error: [$parse:syntax] http://errors.angularjs.org/1.4.4/$parse/syntax?p0=%7b&p1=invalid%20key&p2=2&p3=%7b%7babtninfo.action%7d%7d&p4=%7babtninfo.action%7d%7d"

of course in situation array no longer function string:

var mybtns = [{     label: 'btn1',     action: '$scope.restore()' }];

this simple fiddle shows second case: http://jsfiddle.net/ppe34vlj/3/

remember view needs reference controller via $scope
