this is used when externally the html of an editor has been changed and textAngular needs to be notified to update the model. this will call a $digest if not already happening
function(name){
			if(editors[name]){
				editors[name].scope.updateTaBindtaTextElement();
				/* istanbul ignore else: phase catch */
				if(!editors[name].scope.$$phase) editors[name].scope.$digest();
			}else throw('textAngular Error: No Editor with name "' + name + '" exists');
		}
