IBM Mobilefirst WL.JSONStore fail to store large Json data in windows phone

Question

I am using WL.JSONStore to store JSON data offline. But it gets failed in windows phone when my Json data is more than 2K.

It doesn't through any error and same code works fine in Android and iOS.

Here is my code.

WL.JSONStore
           .get(COLLECTION_NAME)
           .add(response.responseJSON.collection)
           .then(
            function (data) { <code> };
