错误：[$ interpolate：interr]无法插值：{{getButtonText（）}} - AngularJS

Question

我在调用函数时遇到以下错误

Error: [$interpolate:interr] Can't interpolate: {{getButtonText()}} 
TypeError: Cannot read property 'length' of undefined
http://errors.angularjs.org/1.2.3/$interpolate/interr?p0=%7B%7BgetButtonTex…%A0&p1=TypeError%3A%20Cannot%20read%20property%20'length'%20of%20undefined

相同的代码适用于其他页面，但不适用于此页面。

HTML代码：

<td>
<span>
    <img src="images/note.png" class="imgComment" ng-mouseover="this.style.cursor='hand'"
    ng-mouseleave="this.style.cursor='auto'" style="width:30px"
    ng-click="edit({{item.userId}})"></img>
</span>
</td>

Javascript

$scope.edit = function(recordId) {
        var modalInstance = $modal.open({
            templateUrl: 'editView.html',
            controller: 'EditController',
            backdrop: 'static',
            resolve: {
                recordId: function() {
                    return recordId;
                },
                resourceName: function() {
                    return $scope.resourceName;
                },
                deptId : function () {
                    return $scope.dept;
                }
            }
        });

有关可能导致错误的原因的任何想法？
