fix for bugs in PR #555

[misanek]

555 had bugs:

• filtering without render function not working due to wrong ternary condition aData = rowDataRender ? rowDataRender : rowData; correct aData = rowDataRender.length ? rowDataRender : rowData;

• when we have nested objects in row => getProp(rowDataRender, index)

• updated dt render function with all arguments : https://datatables.net/reference/option/columns.render @vedmack I am passing meta object to render function, which should have according to docs these properties: settings : DtSetting, col : column index, row: row index - not sure if I am setting correct one here, from debugging i came up with row: iDataIndex, please check if correct thanks :)

Hey @misanek can you please show me a jsfiddle in which the previous solution didn't worked ?
