Select items in widgets with JS

Fine solution. But to be more understandable for other members I will to add some details

1.) how to find this function if you have no idea where to look for it.

so simple printing of object in the chrome debugging console

e.g. 

console.warn($scope.app.fn);

2.) So here we can print first the $scope and from there we can search for some other functionality  here $scope.app.fn

Now to check if this work we can define the following functions:

$scope.app.fn.clickItemInRepeater = function(item,list,isMultiSelect)
//other name for twx.app
{

 console.log("twx.app.fn.clickItemInRepeater item"); console.warn(item);
 console.log("twx.app.fn.clickItemInRepeater list"); console.warn(list);
 console.log("twx.app.fn.clickItemInRepeater isMultiSelect"); console.warn(isMultiSelect);

}; 
 
$scope.app.fn.clickItemInSelect= function(list,isMultiSelect,value,valueField)
{

 console.log("$scope.app.fn.clickItemInSelect list"); console.warn(list);
 console.log("$scope.app.fn.clickItemInSelect isMultiSelect"); console.warn(isMultiSelect);
 console.log("$scope.app.fn.clickItemInSelect value"); console.warn(value);
 console.log("$scope.app.fn.clickItemInSelect valueField"); console.warn(valueField);
 

}; 
 

3.) And test in the console windows of chrome

3.1)  clickItemInRepeater funciton for dataGrid and repeater widgets

3.2) and for the slect widget:
