[after , forth in comments above, "answer"-worthy may emerging...]

its pulling data , inserting grid. if firing jquery before data loaded, how fix that? have jquery @ bottom of view.

therein appears rub. jquery code in question executes when document loads, appear after document loads, kendo grid makes ajax request data , populate grid.

so see 2 potential options...

perhaps kendo has event or callback can invoke after asynchronous operation completes? don't know product enough demonstrate, suspect product mature enough have that.

as alternative, can make use of .on() higher-level dom element catch events of dynamically created elements. might work:

$(document).on('propertychange input', 'tbody > tr > td > div.col-xs-2 > :text', function (e) {     // ... });

note handler attached document itself, exist when document loads. (technically can attached non-changing element in hierarchy between target element(s) , top level.) , filters events based on selector.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
