'Kendo dropdown giving [Object Object] when binding values dynamically from array

This is my code:

var arr = [];

 for (var i = 0; i < GanttData.length; i++) 
     {  arr.push({"text":GanttData[i].Projectname,"value":GanttData[i].Projectuid});}   

var dropdownlistF = $("#drp_resources").data("kendoMultiSelect");
dropdownlistF.setDataSource(arr);

But it's not working. Any help will be blessing.

Thanks

It depends on how you defined the widget parameters. According to MultiSelect docs the default text field name it will look for in the data is ''(dataTextField), so you need to set it:

$("#drp_resources").kendoMultiSelect({
    dataTextField: 'text'
});
