Angular & textangular typeahead example:

gistfile1.js

//I've changed the typeahead to iterate over an array - this is the __only__ way it'll work with textangular, 
// Textangular does string  manipulation upon select, and cannot work with objects
//viewvalue is http://stackoverflow.com/questions/17837007/in-the-angularjs-bootstrapui-typeahead-whats-viewvalue
// ng-click should probably be typeahead-on-select()
<input data-text-angular data-ng-model="field.name" data-ng-click="itemClicked($index)" name="{{field.caption}}" data-ta-target-toolbars='toolbar' typeahead='option for option in getOptions(field.options) | filter:$viewValue'></input>

//this converts the object to an array, should be self explanatory.
// It's a really good idea to keep you logic _out of_ the html - this increases testability
$scope.getOptions = function(options) {
    var arr = []
    options.forEach(function(object) {
        for (var key in object) {
            arr.push(object[key]);
        }
    })
    console.log(arr)
    return arr;
};
