Dynamically change the start and end properties of DateRangeSlider

I have added a DateRangeSlider widget for x axis to plot timeseries data. But as I am plotting live streaming data (new sample of data at every 15 minutes), the range between start and end range will not accommodate the new data samples.
So I want a way to change the range of the DateRangeSlider dynamically to a new end time as I receive new sample of streaming data. please help me do that.
I am new to the bokeh
Thank you

Just change its end property right were you stream or set the new data.
