Select box in jquery mobile not showing proper selected value but giving proper value.

Select box in jquery mobile not showing proper selected value but giving proper value.

Hi all,
      In my webpage I am creating select box dynamically by providing functionality of add button which will add row. The data binding to select box from web service is proper. But when I select particular value from select box then it is not showing the selected value in select box and surprisingly I can get actual selected value when I call $("selectid").val() function.

Please help me to solve this issue.
