angularjs ng--show is not working as expected -

i getting wrong behaviour ng-show directives.

<span class="spanlabel" ng-show="!minimumcharactersmet()" >you need @ to the lowest degree {{ howmanymorecharactersneeded() }} characters more</span> <span class="spanlabel" ng-show="isnumberofcharacterswithinrange()" >remaining characters: {{ howmanycharactersremaining() }}</span> <span class="spanlabel warning" ng-show="anycharactersover()" >{{howmanycharactersover()}} characters many</span>

when seek input text span counting below warn user of 2 characters minimum, countdown works , after stays there , not hide. sec 1 not show.

here plunker link functions , html. ideas why cant working?

thanks

in add-on @reins said, 2 other statements have these errors:

you're missing same function-calling brackets on anycharactersover

the homecoming statement in howmany functions has bracket error. should

return ( characters < 0 ? math.abs(characters) : 0);

also, homecoming value of isnumberofcharacterswithinrange should be:

$scope.minimumcharactersmet() && !$scope.anycharactersover();

plunker

ps: i'd utilize ng-hide instead of ng-show(!)
