jQuery Grid Plugin - jqGrid

Hi,

I have the following JSON string being parsed for the colModel:

 

[{"attributes":{"type":"Contact","url":"/services/data/v32.0/sobjects/Contact/003o0000004FNNiAAO"},"Name":"Rose Gonzalez","AccountId":"001o00000051kLSAAY","Account":{"attributes":{"type":"Account","url":"/services/data/v32.0/sobjects/Account/001o00000051kLSAAY"},"Name":"Edge Communications","Id":"001o00000051kLSAAY"},"Id":"003o0000004FNNiAAO"}]

The colModel goes like this:

colNames:['ID','Name','Account','Email','Mailing State'],
 colModel:[
 {name:'Id',index:'Id'},
 {name:'Name',index:'Name'},
 {name:'Account',index:'Account'},
 {name:'Email',index:'Email'},
 {name:'State',index:'State'}
 ],
However, when the grid renders it displays [object Object] on the Account Column. How will I make it such that the Account Column should display the Account Name on the Account Column?
