ng-click with a dynamic {{}} string - angularjs

Question

I have a HTML table that has the id set with a databind inside of a ng-repeat
<div class="project" ng-repeat="project in data.projects">
<h2>
{{projectState.name}}
</h2>
<table class="table" id="{{project.name + selectedType}}">
...
</table>
...
</div>
This properly sets the id as expected, but I need to use this id in a ng-click call.
<button ng-click="export({{project.name + selectedType}})">
...
</button>
This produces the error when the page loads
Error: [$parse:syntax] Syntax Error: Token '{' invalid key at column 16 of the expression [export({{project.name + selectedType}})] starting at [{project.name + selectedType}})].
How do I properly reference the databound id of {{project.name + selectedType}} in a ng-click?

Answer 1

Pass project.name and selectedType as 2 arguments to export method :
<button ng-click="export(project.name,selectedType)">
...
</button>
and inside export method concatenate them:
$scope.export = function(name, type){
var val = name + type;
// ...
}
or just remove {{ }} from export

Answer 2

You don't need to give an expression inside of export(). This should be resolved using
export(project.name,selectedType)

angular.module('myApp',[])
.controller('myCtlrl',function($scope){
$scope.projects=[
{ id: 1, name: 'John', address: 'Highway 71'},
{ id: 2, name: 'Peter', address: 'Lowstreet 4'},
{ id: 3, name: 'Amy', address: 'Apple st 652'},
{ id: 4, name: 'Hannah', address: 'Mountain 21'},
{ id: 5, name: 'Michael', address: 'Valley 345'},

$scope.export=function(id){
alert(id);
};
})

<td>{{project.address}}</td>
</tr>
</table>
</div>
</div>

When you are using ng-click, it means you are already in angular scope so you don't need to use {{}} to call a function or evaluate the expression
