Some callbacks are one loading when i am using nevigation

Hi,

I am developing a dash app in which i am navigating to five URLs.
while clicking on a URL some graphs and data should display.
but when i am clicking on URL sometime graph is not coming and sometime data is not coming.
There are some callbacks which are not loading when i click the link.

Is there any way to run all the call back with a link click ?

Thanks in advance.
