Detect Label Change Using - jQuery

Question

I have a lookup field so based on the drop down change the lookup field value changes

 var name; $("#tdf_15").on('DOMSubtreeModified', function () { name = $(this).html(); alert(name); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="tdf_15" class="cell dc" style="background-color: rgb(255, 253, 221);">Dileep Thomas</div> 

So this snippet will alert whenever the lookup field changes , but the alert is working for three times initially when the field is blank and once it is have a value then alert will work for four times at each time we change the drop down. I need to have the alert for only one time also i need to check the value in the variable( name ) is changed or not.

Many thanks in advance if anyone can help me !!
