angular binding to a popover - angularjs

Question

I are trying to bind a $scope.model.value to a popover.
With all the articles I have something working by storing a copy in the $scope then using a watch to update it if it changes who ever that is not a viable solution as I want to take the popover and use it multiple times with different arrays.
my html on the the main body is:
<button href="#" colorpopover
type="button"
class="btn btn-success btn-rainbow"
data-toggle="popover"
data-trigger="click"
title="Button Color"
id="static-color-popover-{{$id}}"
ng-model="model.value.buttonStatic.buttonColor">
Button Color
</button>
my controller has this code
app.directive('colorpopover', function ($compile, $templateCache, $q, $http) {
var getTemplate = function () {
var def = $q.defer();
var template = '';
template = $templateCache.get('/App_Plugins/IBD.ButtonStyles/Popovers/IBD.Color.Popover.html');
if (typeof template === "undefined") {
$http.get("/App_Plugins/IBD.ButtonStyles/Popovers/IBD.Color.Popover.html").then(function (data) {
$templateCache.put("templateId.html", data);
def.resolve(data);
});
} else {
def.resolve(template);
}
return def.promise;
}
return {
restrict: "A",
link: function (scope, element, attrs, model) {
getTemplate().then(function (popOverContent) {
// Make sure to remove any popover before hand (please confirm the method)
var compileContent = $compile(popOverContent.data)(scope);
var options = {
bindToController: true,
content: compileContent,
placement: "left",
html: true,
date: scope.date, };
$(element).popover(options);
});
}
};
});app.directive('colorpopover', function ($compile, $templateCache, $q, $http) {
var getTemplate = function () {
var def = $q.defer();
var template = '';
template = $templateCache.get('/App_Plugins/IBD.ButtonStyles/Popovers/IBD.Color.Popover.html');
if (typeof template === "undefined") {
$http.get("/App_Plugins/IBD.ButtonStyles/Popovers/IBD.Color.Popover.html").then(function (data) {
$templateCache.put("templateId.html", data);
def.resolve(data);
});
} else {
def.resolve(template);
}
return def.promise;
}
return {
restrict: "A",
link: function (scope, element, attrs, model) {
getTemplate().then(function (popOverContent) {
// Make sure to remove any popover before hand (please confirm the method)
var compileContent = $compile(popOverContent.data)(scope);
var options = {
bindToController: true,
content: compileContent,
placement: "left",
html: true,
date: scope.date, };
$(element).popover(options);
});
}
};
});
the template in basic terms
is
<div class="row">
<div ng-repeat="colorGroup in model.value" ng-class="!$last ? '' : 'last'">
<p>{{colorGroup.val1}}</p>
<p>{{colorGroup.val2}}</p>
<p>{{colorGroup.val3}}</p>
the model structure is
$scope.model.value.buttonStatic.buttonColor[val1,val2,val3]
$scope.model.value.buttonStatic.buttonHover[val1,val2,val3]
$scope.model.value.buttonStatic.buttonFocus[val1,val2,val3]
so eventually I want three buttons as a above with each of the tree values passed.
so at present the ng-repeat is repeating on the model.value of the child scope which is a direct copy of the parent.
the value in the template is going to change on the popover so it needs to go back to the parent.

Answer 1

With much trial and error I have solved the problem.
in the directive I needed to tie add these 2 line before the link.
require: 'ngModel', // ensures the model is passed in
scope: { model: '=ngModel' }, //ties the ng-model to the scope of the popover
then all I needed to do was set the ng-model in my button to model.value......
and in the popover template i just use model
