It is possible to use a dynamic parameter and set his scope value?
$scope.testFunc= function(fieldName){
$scope.fieldName = 'Test';
}

var app = angular.module('myApp', []);
function myCtrl($scope, $parse) {
$scope.coolform = {};
$scope.testFunc = function(fieldName){
var model = $parse(fieldName);
model.assign($scope, 'test2');
}
}
or you could use your own directive instead of ng-click, and use = as described here how to set an interpolated value in angular directive?

You need to set like this:
$scope.testFunc= function(fieldName){
$scope[fieldName] = 'Test';
}
If you want nesting like this:
fieldName.secondLevel
you could use:
$scope[fieldName][secondLevel]
Or you use the regex parser used by angular. (I don't know how to use this one...)
EDIT:
The regular expression copied from the sourcecode:
//000011111111110000000000022222222220000000000000000000003333333333000000000000004444444444444440000000005555555555555550000000666666666666666000000000000000777777777700000000000000000008888888888
var NG_OPTIONS_REGEXP = /^\s*([\s\S]+?)(?:\s+as\s+([\s\S]+?))?(?:\s+group\s+by\s+([\s\S]+?))?\s+for\s+(?:([\$\w][\$\w]*)|(?:\(\s*([\$\w][\$\w]*)\s*,\s*([\$\w][\$\w]*)\s*\)))\s+in\s+([\s\S]+?)(?:\s+track\s+by\s+([\s\S]+?))?$/
and the usage:
var match;
if (!(match = optionsExp.match(NG_OPTIONS_REGEXP))) {
throw ngOptionsMinErr('iexp',
"Expected expression in form of " +
"'_select_ (as _label_)? for (_key_,)?_value_ in _collection_'" +
" but got '{0}'. Element: {1}",
optionsExp, startingTag(selectElement));
}
var displayFn = $parse(match[2] || match[1]),
valueName = match[4] || match[6],
keyName = match[5],
groupByFn = $parse(match[3] || ''),
valueFn = $parse(match[2] ? match[1] : valueName),
valuesFn = $parse(match[7]),
track = match[8],
trackFn = track ? $parse(match[8]) : null,
// This is an array of array of existing option groups in DOM.
// We try to reuse these if possible
// - optionGroupsCache[0] is the options with no option group
// - optionGroupsCache[?][0] is the parent: either the SELECT or OPTGROUP element
optionGroupsCache = [[{element: selectElement, label:''}]];
As you see, they use $parse to get the values for the selected expression like fieldName.secondLevel

Thanks for your help, your first solution($scope[fieldName][secondLevel]) its right for me and it worked.
$scope.testFunc = function(fieldName){ $scope[fieldName] = 'Test'; }?
