kendo ui - KendoMobile dataSource didn't initialize properly -

i'm developping little kendomobile webapp. problem quite simple : anytime try initialize datasource setting array data option, datasource remains empty.

here array (screen safari dev console) :

console.log("fournisseursarray -> "); console.log(fournisseursarray);  

now structure of objects :

in opinion both seems correct in fact : when use objects array, shows me want guess works fine.

but if simple, wouldn't have here, so...

this how declare datasource :

datasourcemap = new kendo.data.datasource({     data: fournisseursarray }); 

finally when put log on datasource :

console.log(datasourcemap); 

if knows problem, i'll him share knowledge me

the kendo ui data source remain empty unless call read or fetch methods. in short call fetch or read before accessing data.
