Range Slider Thumb not stop where user want to stop

Hello
When I select thumb from left and right both side but label not stop where I want, after few second both thumb go on its original position so low and high value pick it's old value.

So I need new value where my label stop. How can I get It?

you need to give default values to high and low first...
