I´m working with Kendo Ui Gantt AngularJS

How to execute the update function and get, again, I need it for a custom function

I need something like that
update ();
get ();

I have a problem with kendo AngularJs, I´m working with Kendo Gantt, in the section when the resources are assigned, they are repeated, for example, I have TASK 1 and I assigned the resource Manuel, and I have the  TASK 2, I assigned the reosurce Daniel, in the TASK 2 is assigned the resource Manuel and Daniel, and this happen en all tasks. 

Add a zoom slider so that the tasks rows /time columns will be smaller.  Showing more or less tasks and time

Currently gantt resource name template is a hardcoded as "{name} [{percents}]" and to change it we need to patch kendo scripts (in our case to remove percents part)

To configure the component, I would like to be able to have and customize tooltips for the views when I am performing a resize or move on the tasks. I have looked through the documentation and all I could find one option called resizeTooltipFormat.

That is a problem for me because, first, it's only a format for the dates and not a full template, and second, there is no option to do the same for the move action.
