How to add array new key value ( javascript ) ?

sample image http://i.hizliresim.com/dj3OLn.png

example this my array

source.localdata[0].c_Id="2d5955ee-415b-470a-8700-3ae65ee122db"
                    Name ="mike"
                    LastName="jonas"


source.localdata[1].c_C_ID"b851c285-035f-4a51-8237-1e3c3528e089"
                    Name ="richard"
                    LastName="gere"

and I want to enter key and value data

source.localdata[0].Address = "mike for address"
source.localdata[1].Address = "richard for address"

..more

output

source.localdata[0].c_Id="2d5955ee-415b-470a-8700-3ae65ee122db"
                    Name ="mike"
                    LastName="jonas"
                    Address = "mike for address"

source.localdata[1].c_C_ID"b851c285-035f-4a51-8237-1e3c3528e089"
                    Name ="richard"
                    LastName="gere"
                    Address = "richard for address"

I wrote this code but I am getting error JavaScript runtime error: Object doesn't support property or method 'push'

function dataSourceCompare(newdata) {

for (var i = 0; i < source.localdata.length; i++) {

    for (var j = 0; j < newdata.dynamicColumns.length; j++) {

        if (crewItems[i].c_C_ID === newdata.dynamicColumns[j].ColumnValue) {
            source.localdata[i].push([newdata.dynamicColumns[j].ColumnName, newdata.dynamicColumns[j].ColumnValue]);

        }             
    }                                                   
}

}

thank you

Array.push() is used to add new elements to an array, and cannot be used on a plain javascript object. What you want to do is add a new propriety to an object, with a dynamic property name, and here's how to do it: 

source.localdata[i][newdata.dynamicColumns[j].ColumnName] = newdata.dynamicColumns[j].ColumnValue;
